the reaction. This can be seen as an instant change in colour‚ from a colourless solution‚ to a deep purple coloured solution. This change in colour denotes the completion of the reaction. Factors affecting the rate of reactions: All chemical reactions occur at a definite rate under particular conditions. In order to increase the rate at which reactions occur‚ the frequency at which reacting molecules collide must be increased. This may be achieved in a number of ways: 1. By

Kinetics of the Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2

Clock reactions If you choose a project that explores the kinetics of a chemical reaction you will need a way of measuring the rate of the reaction. Clock reactions provide an interesting way of doing this for some systems. In a typical reaction the first part of a graph showing the concentration of product against

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

Background research: The Briggs-Rauscher reaction The Briggs-Rauscher reaction also known as the oscillating clock is a demonstration of a chemical oscillator reaction. It happens when three prepared colourless solutions are mixed together and this will slowly turn into an amber colour to deep blue clear for approximately 3-5 minutes as it repeats itself. The reaction ends up as a blue-black
