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

Tesco’s organisational structure has the customer at the top. Tesco needs people with the right skills at each level of this structure. There are six work levels within the organisation. This gives a clear structure for managing and controlling the organisation. Each level requires particular skills and behaviours

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

Trade restrictions: Tesco also have to make sure that they adhering to any trade restrictions in place in the United Kingdom. Economic climate: Because of the economic climate Tesco could be struggling to give out jobs to people which means less stores across the UK and even stores having the possibility of being closed down to

Porters Generic Strategies Strategy concerns two factors‚ deciding where you want a business to go‚ and deciding how to get there. According to Grant (2010) “A firm can achieve a higher rate of profit (or potential profit) over a rival in one of two ways: either it can supply an identical product or service at a lower cost‚ or it can supply a product or service that is differentiated in such a way that the customer is willing to pay a price premium that exceeds the additional cost of differentiation

Tesco’s success depends on people; the people who shop with them and the people who work with them. If their customers like what Tesco offer then they are more likely to come back and shop their again. If the Tesco team find what they do rewarding they are more likely to go that extra mile to help their stores. Tesco want to expand and extend existing

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
