A chemistry student wants to investigate the activation energy for a reaction between hydrogen and chlorine gases. The student measures the initial and final temperatures of the reaction mixture, and the rate of gas evolution. Based on this information, the student wants to calculate the activation energy of the reaction using the Arrhenius equation. What steps should the student follow to determine the activation energy of the reaction?
