An investigator is conducting kinetic experiments on a first-order reaction A?P for which the rate coefficient at 298 K is k0 = 0.001 s^-1. The activation energy for the reaction is found to be 40 kJ mol^-1. Assume that a simple Arrhenius expression gives the dependence of k upon temperature. The investigator runs the reaction in a container whose temperature is increased to 500 K. What is the change in the half-life time?
