1. Within direct simulation Monte Carlo (DS3V) I am having problems determining the pre-exponential factor inside of the Arrhenius equation. I have all fields of data other than that and the reaction rate constant which I cannot find. This is for a protium medium with neutrons being inserted. 2. The equation: k(T) = AT^-E(subscript a)/(RT) Where k(T) is the reaction rate constant that depends on temperature, T is the absolute temperature, E(subscript a) is the activation energy, and R is the universal gas constant. 3. k(T)=0.9312023648A is as far as I could get. Anyone know how to proceed? Thanks!
