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

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

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

1.0 Introduction Strategy is a long term directions for companies. Bennett (1996‚ cited by Cousins 2000) describes strategy as: “The word strategy is used to describe the direction that the organisation chooses to follow in order to fulfil its mission”. Today‚ strategies are vital for businesses‚ in many cases it helps to achieve a competitive advantage. Increasing competition in most sectors and technological development has led to accelerated changes in the global economy. In order to meet

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

History of Clocks and the Impact of Electricity on them. Introduction: In this poster we are going to show you the history and the development of the clock through time and how it has impacted society. We will also show how electricity has affected the development and effectiveness of clocks. Sun clock: One of the first clocks on record is the sun clock. Sun clocks basically work on the principle that the position of a stationary object’s shadow will be in the same place at a certain
