You can write the rate law for the decomposition of azomethane as

when n is the order of the reaction. When you divide the rates at various times by the concentrations raised to the correct power n, you should get the same number (the rate constant k). Verify that the decomposition of azomethane is first order by dividing each average rate in a time interval (obtained in Problem 13.95) by the average concentration in that interval. Each calculation gives nearly the same value. Take the average of these values to obtain the rate constant.
