Determination of Rate Law

Abstract: A solution containing potassium iodide was mixed with a hydrogen peroxide solution to determine the rate law for the reaction between hydrogen peroxide and potassium iodide at room temperature and the activation energy, Ea, of the above reaction. Potassium iodide and hydrogen peroxide react according to the following equation: We found the experimental rate law for this reaction to be and the activation energy of the reaction was calculated to be and the Arrhenius pre-exponential factor (A) of . Introduction All chemical reactions require some minimum amount of energy to transform the reactants into products. The rate of the reaction is the rate at which the products are formed from reactants. At constant temperature, the rate of a chemical…
