BRIGGS RAUSCHER OSCILLATING CLOCK COURSEWORK Aim: To investigate the effect of temperature on the rate of reaction. To investigate the order of reaction with respect to hydrogen peroxide and ethanoic acid (acetic acid) by the use of an oscillating clock reaction. To determine the activation enthalpy with and without catalytic ions and use this to compare the effectiveness. To investigate the rate equation‚ rate constant and possible mechanism for this reaction. Background research: The Briggs-Rauscher

outlet in the United States‚ Zara Home could view every American internet user as a potential customer. However‚ Zara Home products are targeted toward women in the age group of 18-34. 27% of the total American population online falls in that age bracket3‚ almost evenly distributed between men (51%) and women (49%)4. The target audience for Zara Home can therefore‚ be narrowed down to approximately 13-14% of the American population - women who actively use the internet. The Zara Home target is extremely

increasing the concentration of KIO3‚ 0.15M concentrations resulted in times of 45.77 and 150.47 when tested twice which was unexpectedly higher than 13.68s at a concentration of 0.1 (Table 1). Similarly‚ raising the concentration of NaHSO3 decreased the clock period with the exception of the 0.2M concentration as it had the lowest time of 15.39s when 0.4M was expected to be lower (Table 2) These inconsistencies for the concentration data may have been due to measurement errors during the experimental process

Project Executive Summary In recent months‚ Zara has observed the demand for a second retail shop in Bulgaria‚ located in Plovdiv. Therefore‚ the business aspect for this project is the growing and developing of the trademark Zara. The fact that Zara already has its first shop in Bulgaria (Sofia) and the profits are really higher‚ leads to the assumption that the project for opening a second shop will gain even higher results in the future. What is more‚ there is an analysis that shows the more

Lab #3: Method of Initial Rates: Iodine Clock Introduction The detailed system of steps in a reaction is called the reaction mechanism‚ and it is one of the principal aims of chemical kinetics to obtain information to aid in the elucidation of these mechanisms in order to better understand chemical processes. Reactions usually occur in a stepwise manner with each step proceeding at a different speed. If the rate of reaction is slow enough to measure‚ this is indicative of a step much slower

Experiment 16: Kinetics: The Iodine Clock Jane Smith Purpose: The objective of this experiment was for students to apply their knowledge of kinetics and rate laws in order to determine the rate of a chemical reactions‚ activation energy‚ and frequency factors of those reactions. Specifically‚ this experiment was performed using a series of solutions with varying concentrations of KI‚ Na2S2O3‚ and (NH4)2S2O3 . Students recorded time elapsed to observe physical evidence of a reaction taking place
