Chemistry Extended Essay Essay To investigate the effect of 2-bromo-2-methyl propane concentration and temperature of the system on the rate of reaction of solvolysis of 2-bromo-2-methyl propane in 90% ethyl alcohol Done by: Habib Iscandar Hinn Friends Boys School June 22, 2007 To investigate the effect of 2-bromo-2-methyl propane concentration and temperature of the system on the rate of reaction of solvolysis of 2-bromo-2-methyl propane in 90% ethyl alcohol Introduction: The major product of the solvolysis of t -butyl chloride in 70 % water 30 % acetone is t-butyl alcohol, with a small amount of isobutylene being formed as a by product And this is with accordance of first order kinetic and suggests a two step mechanism in which the rate determining step consists of the ionization of t-butyl chloride, and in this mechanism a carbonium ion is formed as inter- mediate and this bonds immediately to near by nucleophile (in this case nucleophile is a neutral molecule) the initial product is t-butyl carbonium ion. Note1: if the nucleophile is neutral the product will be charged since the leaving group takes both bonding electrons away with it So chemists have proposed to general types of mechanism: 1- Nucleophilic substitution Sn1 The ionization step in a Sn1 reaction is endothermic and much slower than the exothermic neutralization of carbonium ion by a nucleophile. And so the rate determining step being the unimolecular ionization of the t-butyl chloride equation 4, and as a result, the overall rate of reaction is not affected by changes in the concentration or kinds of nucleophilic reagents present. Note2: the factor which determines the mechanisms employed is typically the nature of the substrate it self and not the particular nucleophile Note3: if the sum of the energy of the product is lower than the energy of the reactant the reaction is exothermic, and if the product have higher energy than the reactant the reaction is endothermic. 2- Elimination E1 (elimination unimolecular) And because t-butyl chloride acts as a Lewis acid (an electrophile) and combines with a nucleophile to give a substitution product, so the major product of the solvolysis of t-butyl chloride in water-acetone solvent is t-butyl alcohol. (Note4: electrophile: an electron deficient atom, ion or molecule that as affinity for an electron pair, and will bond to a base or nucleophile.) (Note5 : nucleophile: and atom, ion , or molecule that has an electron pair that may be donated in forming covalent bond to an electerophile.) Evaluating the mechanism: The only reactant that is undergoing change in the rate determining step is t-butyl chloride and so such reactions is a unimolecular and follow a first order equation (Sn1, E1). This means that the rate of the reaction varies directly with the concentration of t- butyl chloride. And since nucleophilic only participate in the fast second step, so their relative molar concentrations rather than their nucleiophilities are the primary product determining factor, and by using nucleophilic solvent like water, so its high concentration will assure that alcohols are the major product, and because water have a high dielectric constant (e=81) so water molecule tend to orient them-selves in such a way as to decrease the electrostatic forces between ions. And an important factor is the salvations which refer to water molecules ability stabilize ions by encasing them in a sheath of weakly bonded solvent molecules: 1- Anions are solvated by hydrogen bonding, 2- Cations are solvated by nucleophilic sites on water molecule (oxygen). And in this case of t-butyl carbonium ion the nucleophiles form strong covalent bond to carbon and converting the intermediate to a substitution product. The reaction mechanism is a sequential account of each transition state and intermediate in a total reaction, the over all rate of reaction is determined by the transition state of highest energy in the sequence, so the rate determining step is the rate determining step for both the Sn1 and E1 for t butyl chloride. (Note 6: the water soluble organic solvent acetone is used to keep a reasonable concentration of t-butyl chloride in solution) The balance equation for t-butyl chloride solvolysis in water-acetone solvent is: The effect of concentration on the solvolysis of t-butyl chloride in 70 %water 30 %acetone solvent. As the reaction proceeds the solution becomes increasingly acidic until all of the t -butyl chloride has reacted and all HCl that can form has formed. So we will monitor the reaction by allowing HCl formed to neutralize a predetermined amount of NaOH. An indicator dye (bromo-phenol blue) will change color when the NaOH has been neutralized, and clocking of the reaction should begin at the instant. So according to kinetic measurements: Rate of reaction = K [t butyl chloride] Where K is the specific rate constant in S -1 and [t butyl chloride] is the concentration of t-butyl chloride in M. Our kinetic measurement will depend on the determination of the amount of HCl produced by the reaction, so by monitoring the color change of the acid base indicator, we will determine the time required for 10% of t-butyl chloride to hydrolyze by having 10 % as much NaOH present as T-butyl chloride. Rate = d [Rcl] dt ; Where Rcl = -dt [Rcl] = K [Rcl] dt Rearranging, d [Rcl] = -K dt [Rcl] And integrating for t=0 to t=t will give; = Ln [Rcl] t Ln [Rcl] 0 = Kt 2.303 Log [Rcl] 0 = Kt [Rcl] t 2.303 Log [Rcl] 0 = Kt [Rcl] t Where [Rcl] 0: is the molar concentration at time t = 0 [Rcl] t: is the molar concentration at time t = t Two methods to calculate K 1- since the equation Kt = 2.303 Log [Rcl] 0 [Rcl] t Is an equation of a straight line (y=mx+b) with slope k. and intercept =0, a plot of 2.303 log [Rcl] 0 / [Rcl] t versus t should yield a straight line with slope k. 2- if the solvolysis reaction run to 10% completion Then, [Rcl] = 0.90 [Rcl] 0 Kt = 2.303 Log [Rcl] 0 = 2.303 log (1.11) 0.90 [Rcl] 0 And therefore, K = 0.104 T So by finding the value of K and compensate it in the rate of reaction equation Rate = K[Rcl] where the concentration of Rcl is known we can calculate the value of the rate of reaction and we will see its effect on the solvolysis of t butyl chloride in 70% water 30 % acetone solution. The effect of temperature on the solvolysis of t -butyl chloride in 70%water 30%acetone solvent. In nearly every instance an increase in temperature causes an increase in the rate of reaction, because the total fraction of all of the t butyl chloride 1molecules having energies equal to or greater than activation energy (Ea) Corresponds to the shaded portion of the area under the curve increases by increasing the temperature and by comparing the area for two different temperature, we see that the total fraction of t- butyl chloride molecules with sufficient kinetic energy to undergo reaction increases with increasing temperature and consequently, so does the reaction rate. Note7: changing the concentration affects the rate of reaction changing the temperature affects the rate constant as well as the rate. By finding the values of reaction rate constant K for different concentration of t-butyl chloride and different reaction temperature, we will find the effect of temperature on the solvolysis of t-butyl chloride in water acetone solvent. Quantitatively, K (s-1) is related to Ea and T by the equation K1 = Ae-Ea/RT1 1 Ea is the activation energy, in joule / mole. (Jmol-1) A is a proportionality constant, in s-1 R is the gas constant = 8.314 Jmol-1K-1 e is the base of the natural logarithms. T is temperature in Kelvin. This relation ship is known as Arrhenius equation We measure Ea by taking the natural logarithm of eq.1 Ln K = ln A Ea RT Thus, a plot of ln k versus 1/T gives a straight line whose slope is equal to -Ea/R and whose intercept with coordinate is ln A Note8: Ea is the activation energy, a constant characteristic of the reaction We can calculate the rate constant at some specific temperature if Ea and K at some other temperature are known. For any temp. T1 (known), Ea (known), K1 (known) K1 = A e -Ea/RT1 For any other T2 (known); (K2 unknown) K2 = A e -Ea/RT2 By dividing K1 over K2 K1 = A e -Ea/RT1 K2 A e -Ea/RT2 Taking natural logarithm of both sides, we get Ln K1 = Ea (1/T2 1/T1). K2 R Or in common logarithms (base 10 logarithms) gives: Log K1 = Ea (1/T2 1/T1) K2 2.303 R And by finding the value of K2 we will be able to find the rate of reaction at T2 and we will find the effect of temperature on the rate of solvolysis of t butyl chloride in 70 % water 30 % acetone solution. By finding the values of reaction rate constant K for different concentration of t-butyl chloride and different reaction temperature, we will find the effect of concentration and temperature on the solvolysis of t-butyl chloride in water acetone solvent.

Musical Expression and Musical Meaning in Context :: Music Philosophy Essays

Musical Expression and Musical Meaning in Context 1. Some preliminaries. There is a growing body of work in the philosophy of music and musical aesthetics that has considered the various ways that music can be meaningful: music as representational (that is, musical depictions of persons, places, processes, or events); musical as quasi-linguistic reference (as when a musical figure underscores the presence of a character in a film or opera), and most especially, music as emotionally expressive. Here I will focus on the last topic, for I believe it will be useful for researchers in music perception and cognition to avail themselves of the distinctions that aestheticians have worked out regarding the musical expression of emotion. Now we often say that music is "expressive," or that a performer plays with great expression, but what exactly do we mean? There are at least two things one may be saying. First, one may be praising a performer for their musical sensitivity, that he or she has a keen sense of just how a passage is supposed to be played. Such praise is often couched in terms of the performer's "musicality" (in statements that border on the oxymoronic, as when one says that a performer plays the music very musically). Such praise may also be couched in terms of expression--i.e., that a performer plays "expressively." I have little to say about these attributions, save that they are often linked to the second thing one often means when speaking of the music or a performance being expressive: an expressive piece or performance is one that recognizably embodies a particular emotion, and indeed may cause a sympathetic emotional response in the listener. Thus if one plays "expressively," this means that the music's particular emotional qualities--its sadness, gaiety, exuberance, and so forth, are amply conveyed by the performer. Before we discuss those emotional qualities a number of other preliminary remarks are in order. When we speak of the expressive properties of music, these are distinct from the expressive properties of sound. Sounds may be loud, shrill, acoustically rough or smooth, and so forth. These acoustic qualities have expressive correlates and may trigger emotional responses, and of course one cannot have music without sound. But musical expression is more than this: it requires the attention to the music qua music, rather than as mere sounds. The opening "O Fortuna" of Carmina Burana may shock (and indeed scare) the listener due to its sudden loudness (especially when the bass drum starts whacking away), but this shock isn't a musical effect--we get the same reaction when we here a sudden "bang" at a fireworks display or when a car backfires.

Kfc Versus Mcdonald’s

INTRODUCTION 1. 1 Background KFC According to the information, â€Å"Kentucky Fried Chicken (KFC) is a chain of fast food restaurant based in Louisville, Kentucky, United States that selling Kentucky Fried Chicken around the world. † It had been rated at number 60 as the world most famous brand by BusinessWeek. For KFC, fried chickens was the food they primary focus to sells. â€Å"Their basic products included chicken pieces, salads, sandwiches, desserts and some roasted and grilled chicken cuisines too. † Besides that, the beef and pork based products also offered by KFC outside the USA.The first idea of KFC’s fried chicken actually is in 1930 but it was only founded in 1952 by Colonel Harland Sanders, who was born on September 9, 1980 in Indiana, America and he was the man who developed the secret recipe which blends of 11 herbs and spices for making Kentucky Fried Chicken and this secret recipe still used today. Nowadays, KFC has more than 15,000 outlets in 1 05 countries around the world. In 1973, the first KFC restaurant in Malaysia was opened at Jalan Tunku Abdul Rahman, Kuala Lumpur. In overall, KFC currently has 445 outlets in Malaysia and it had become the largest fast food chain in Malaysia.McDonald’s According to the information, McDonald’s is the world’s largest chain of fast food restaurant based in Des Plaines, Illinois in 1955 to today that selling hamburgers around the world and it had been rated at number 9 as the world most famous brand by BusinessWeek. â€Å"For McDonald’s, foods that primarily sells by them are hamburgers, cheeseburgers, chicken, French fries, breakfast items, soft drinks, shakes and desserts. † But nowadays, due to the changing of customers’ tastes, the restaurant menu which are included salads, smoothies and fruits have been expanded by McDonald’s company.The founder of McDonald’s is Ray Kroc although the first concept of McDonald’s was act ually introduced by sibling Dick and Mac McDonald and they built the first McDonald’s restaurant in 1940 in San Bernardino, California. In 1954, Mr. Ray Kroc acquired franchising rights from Dick and Mac McDonald and a McDonald’s franchise was opened on 15 April, 1955 and later bought out the McDonald’s share of the McDonald brothers. The McDonald’s Corporation was then founded in 1955 and it was expanded by Ray Kroc. Nowadays, McDonald’s has more than 31,000 outlets in 109 countries around the world.In 29 April 1982, the first McDonald’s restaurant in Malaysia was opened at Jalan Bukit Bintang, Kuala Lumpur. In overall, McDonald’s currently has 200 outlets and about 20 to 25 outlets are being expanded annually. 1. 2 Problem This report has been written to compare the customer service of fast food restaurants in Malaysia: KFC versus McDonald’s. Nowadays, increasing competitive challenges have been faced by the fast food restaur ants in Malaysia such as restaurants KFC and McDonald’s. In order to satisfy the customers at a fast food restaurant, excellent customer service should be provided to customers by the management and the staff.Because beside the food quality, the standardize customer service that provided by fast food restaurants is expected by the customers. Currently, customer service is one of the factors that determine the customer satisfaction and it will directly affect the business of their fast food restaurants. However, recently the fast food restaurants are lack of customer service. The standardization in franchising business format does not ensure the standardization of customer service within the fast food restaurants due to some outlets are not able to follow up the same standards for customer service in franchise system. . 3 Purposes The purposes of this report are firstly to investigate the customer satisfaction with the customer service that is provided by KFC versus McDonaldâ €™s and secondly, to find out why students from Tar College prefer McDonald’s than KFC. Lastly, is to find out what aspects of customer service that provided by KFC and McDonald’s affect their business. 1. 4 Methods 1. 4. 1 The Sample The sample size of 30 was randomly selected, between the age of 18 to 22 from different gender. They are all students from School of Business Studies (Banking and Finance), Tar College KL Main Campus. 1. 4. 2 Data Collection ) Survey 30 sets of questionnaires were distributed as a source of primary data at Tar College KL Main Campus. These questionnaires consisted of 8 questions which focused on the customer satisfaction with the customer service that is provided by KFC versus McDonald’s, the reasons why students from Tar College prefer McDonald’s than KFC and what aspects of customer service that provided by KFC and McDonald’s affect their business. A clean copy of the questionnaire can be found in Appendix A. b) Internet Search The source of secondary data is the information obtained from the internet research.Information was gathered on the customer service that is provided by KFC and McDonald’s from the Internet. Various websites of KFC and McDonald’s were browsed through for this research. 1. 5 Scope This report investigates the customer service that provided by KFC and McDonald’s only. Other fast food restaurants are not included in this report. It focuses on the customer satisfaction with the customer service that was provided by KFC versus McDonald’s, the reasons why students from Tar College preferred McDonald’s than KFC and what aspects of customer service that provided by KFC and McDonald’s affect their business.The survey questions were distributed on 28 May 2012 at Tar College and collected back after the respondents finished their survey and only had 30 Tar College KL Main Campus students of School of Business Studies (Banking and Finan ce) were surveyed for this report. 2. FINDINGS 2. 1 Findings from Survey / Questionnaire Pie Chart 1. 1 The chart shows the frequency of TARC students go to fast food restaurant. 30 respondents were surveyed. As shown in the pie chart 1. , there is a total of 12 respondents who were going to the fast food restaurant once every two weeks, which occupied 40% of the 30 respondents. There are also 8 respondents which equal to 27% of the 30 respondents are going to the fast food restaurant once a month. Besides this, there are 6 respondents, 20% of the 30 respondents go to fast food restaurant once a week. For the remaining 4 respondents, there are 3 respondents go to fast food restaurant less than once a month and only 1 respondent go to fast food restaurant for two or three times a week.This pie chart shows that, most of the TARC students are going to fast food restaurant once every two weeks as it occupied 40% of the 30 respondents and the least of the TARC students are going to fast food restaurant for two or three times a week as it only occupied 3% of the 30 respondents. Pie Chart 1. 2 The chart shows the fast food restaurants that TARC students prefer to go. 30 respondents are being selected for a survey of either KFC or McDonald’s they will prefer to go. As shown in the pie chart 1. 2, there are 26 respondents which occupied a large portion of 87% among the 30 respondents are prefer to go to McDonald’s.Whereas the remaining of 4 respondents which only occupied a small portion of 13% among the 30 respondents is prefer to go to KFC. There are large portions of TARC students prefer to go to McDonald’s rather than KFC. These may be affected by the customer services, prices and the set menu provided by the McDonald’s are better than KFC. Bar Chart 1. 1 The chart shows the customer satisfaction with the customer service that is provided by KFC versus McDonald’s. 30 respondents were surveyed. As shown in the bar chart 1. 1, there is a total of 17 respondents who satisfied with the customer service that is provided by KFC.Whereas there is a total of 13 respondents who are not satisfed with the customer that is provided by KFC. On the other hand, there is a total of 26 respondents who are satisfied with customer service that is provided by McDonald’s and the other 4 respondents are not satisfied with customer service that is provided by McDonald’s. This bar chart shows that, customer service provided by McDonald’s are more satisfied by the respondents.

From the respondents view, we found that the consumers are more satisfied with the ordering service in McDonald’s compared to KFC. Ordering service is important to maintain the business because if the food order was wrong and incomplete, this may cause consumer resentful with the service that provide by the fast food restaurant.Next, the waiting time after service play an important role in the fast food restaurant and this is the reason why consumers like to have their meal in fast fo od restaurant because usually most of them are students or workers who are in the hurry so they need to get their meal in the shortest time. Based on the respondent view, the waiting time after ordering food in McDonald’s is faster and shorter than KFC, this show that respondents are more preferred to have their meal in McDonald’s.Moreover, the attitude of the staff when taking order from the consumer will affect the reputation of the restaurant. Due to the survey, staff from McDonald’s are more patient when taking order than staff from KFC. In addition, Malaysia was a multi-racial country, so the communication skills are important when communicate with their customer. The respondents from survey feel that communication skills of McDonald’s are better than KFC since the McDonald’s can speaks in multiple languages. Nowadays, apart from drive hrough and having meal in restaurant, most of the fast food restaurants are provided telephone service for co nsumer to ordering food. For the staff who responsible to the telephone service, they need to answering the phone with the polite attitude and the speed of the staff speaking was important to ensure that the customer can listen clearly and understand. According the result of survey, respondents are more likely to use the telephone service of McDonald’s compared to KFC. Furthermore, friendly and polite staffs are according to the staffs who work in a fast food restaurants such as McDonald’s and KFC.This refers to their respond on how to serve their customer, a staff should be able to respond well such as the way they welcome their customers, taking order and answer customer question. When a staff from a particular fast food restaurant such as McDonald’s and KFC performs nicely and in a courteous behavior, this leads to frequent visit of the customers to the particular fast food restaurant. As a result from survey, we found that respondents are more preffered to M cDonald’s customer service compared to KFC.Lastly, the avaibility of sauces, tissue and utensils also act an important role in a fast food restaurants because some of the customer would like to have some sauces to favor their food and they may need some tissue after taking meal. Refer to the survey, most of the respondents are more satisfied with the facilities of the McDonald’s compared to KFC. In short, the customer services of the McDonalds are more prefered by customers if compared to KFC. Bar Chart 1. 4 The chart shows the methods that are suitable for KFC and McDonald’s to improve their customer services. 0 respondents were based on their opinion and preferences to respond how to improve the customer services for KFC and McDonald’s. Based on the survey, 17 out of 30 respondents had been choose to train the staff to be polite always for KFC and 8 respondents for McDonald’s. On the other hand, 15 of respondents had responded to train their staf f to use language to promote a good customer services and 16 respondents had choose it for McDonald’s. 9 respondents had responded to train their staff to deal with customers complaints for KFC and 8 respondents for McDonald’s.There are 20 respondents had choose to increase the speed of services for both KFC and McDonald’s. 8 respondents responded that communicate more with customer are suitable in to improve customer services for KFC and 9 respondents for McDonalds. KFC and McDonald’s both have 11 respondents respond on upgrade the staff appearance and image. Upgrade of delivery services for KFC have 12 respondents and for McDonald’s have 13 respondents. 8 respondents had responded that KFC need to upgrade their telephone services and 15 respondents responded that McDonald’s need to do so to improve their customer services.It is highly likely most of the respondents responded that the KFC and McDonald’s need to increase the speed of services because it was probably due to the staff served the staff slowly and the waiting time is long. For KFC, there are very least respondents unsatisfied with the telephone services skills and for McDonald’s there are only 8 respondents unsatisfied with the staff manners and attitude. As a conclusion, KFC and McDonald’s and should focus more on the speed of their services and the staff appearance and image so that it can help to improve their services. . 2 Findings from the internet From our secondary research, we found that the customer service provided by McDonald’s is better than KFC. Due to the good customer service provided by McDonald’s, many customers prefer McDonald’s to KFC. For KFC, we found that there is a declining service standards. A lots of complaint about KFC. Our research shows that, many customers end up with disappointed with the customer service provided by KFC after they visit it. Many customers complainted that the staff a re impatient when taking their orders and poor manners.One of the examples is â€Å"on 6 February, 2012 an serious incident was happened at KFC i-city, Shah Alam Malaysia. The KFC’s staff was fighting and hitting their customer. † Customers are paid to eat at KFC, no one deserve to be treated like that. Besides that, the food that customers orders was not correct. For example, â€Å"a customer ordered a bucket meal: 5 grilled and 5 original but when he opened the bucket, his half-grilled half-original recipe order was replaced by an all-grilled bucket. † These all indicated the bad customer service from KFC so customers less prefers go to KFC than McDonald’s.In contrast, McDonald’s less likely to have these kinds of problems.

RECOMMENDATIONSAccording to the conclusion, we are recommend that the customer services for both fast food restaurants, McDonald’s and KFC which were not satisfied by customers should be improved to achieve a higher level or more preferable and satisfied by customers. For McDonald’s, we are recommend that the communication skill of the staff should improve by training their staff to use language that promotes good customer services based on the respondents view. The McDonald’s sta ff should not talk too fast or too slow to the customers so that the customers can hear clearly what they talking about.Moreover, McDonald’s should communicate more with their customers such as distribute a survey and request a feedback.

The delivery staff must drive carefully to avoid accident so that the customers can trust on them.Lastly, McDonald’s also can upgrade their telephone service skills. When the customers call for the delivery, the staff must explain clearly to the customers about their menu and double confirm with the menu order by the customers. McDonald’s also can provide more type of language for the customers so that they can cho ose the language they know. Besides that, for KFC, the respondents have gives some opinions and comments which the KFC’s staff needs to increase the speed of services to ensure that the customers no need to wait and queue for a long time to get the food.The KFC’s staff also needs to be polite when serving their customers. The KFC can conduct a programme which the main objective is to train their staff to be polite when serving customers to avoid their staff argue with the customers. This can decrease the complaints from the customers. When they receive complaint from customers, they need to know how to deal with the customers promptly. So, KFC may give the empowerment to their staff and give training to their staff how to make decision when dealing the complaint from customers.Lastly, KFC need to upgrade their staff’s appearance and image. For example, KFC can set up guidelines for their staff how to improve their image and appearance. If the staff looks tidy an d clean, customers will be more confident to buy their products. On the other hand, the customers will never buy their products if their staff looks messy and dirty. Therefore, we suggest that the recommendations mentioned above might be encouraged more customers to buy their products and be more satisfy when buying their products as well as both McDonald’s and KFC improved their customer services.

El and La With Country and Place Names in Spanish

Use of the definite article, the equivalent of the in English, with country or place names is much more common in Spanish than in English, although it is not often required. The definite articles in Spanish are el and la, both meaning, the. El is used to modify masculine nouns or places. La is used to modify feminine nouns or places. The only case where the definite article is used in almost all cases is if you are modifying a country or place with an adjective or a prepositional phrase. For example, Soy de Espaà ±a means Im from Spain, and no definite article is needed. But, if the place becomes modified with an  adjective, like being called, beautiful, then the definite article is retained. For example, Soy de la Espaà ±a  hermosa, which means, Im from beautiful Spain. Another example, there is no definite article in Mà ©xico es  interesante, meaning, Mexico is interesting, but, there is the definite article in El Mà ©xico del  siglo  XVI era  interesante, meaning,  16th-century Mexico was interesting.
