Question 2 / 2

AQA Jun 2016 Paper 4 Q7 do not write outside the box the initial rate of the reaction between gases d and e was measured in a series of experiments at a constant temperature the results are shown in table table expt initial d mol dm initial e mol dm initial rate mol dm s a deduce the order of reaction with respect to d and the order with respect to e marks order with respect to d order with respect to e space for working b suggest why initial rates of reaction are used to determine these orders rather than rates of reaction at other times during the experiments mark c state how the initial rate is obtained from a graph of the concentration of the product against time marks turn over wmp jun chem do not write outside the box the reaction between propanone and iodine in the presence of hydrochloric acid was studied at a constant temperature ch coch i ch coch i hi the following rate equation was deduced rate k ch coch h a suggest why the order with respect to iodine is zero mark b in an experiment the initial concentrations of propanone iodine and hydrochloric acid were as shown in table the initial rate of reaction in this experiment was mol dm s table initial concentration mol dm ch coch l h use the data in table and the rate equation to calculate a value for the rate constant at this temperature give units with your answer marks wmp jun chem
