Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)
