Learning Goal: To use the Arrhenius equation to calculate the activation energy. As temperature rises, the average kinetic energy of molecules increases. In a chemical reaction, this means that a higher percentage of the molecules possess the required activation energy, and the reaction goes faster. This relationship is shown by the Arrhenius equation k = Ae Ea/RT where k is the rate constant, A is the frequency factor, Ea is the activation energy, R = 8.3145 J/(K mol) is the gas constant, and T is the Kelvin temperature. The following rearranged version of the equation is also useful: In = 1 1 (*)(*)(*-*) R where k is the rate constant at temperature T1, and k2 is the rate constant at temperature T. the initial and the final temperatures as defined in part A.
