Where K is the reaction rate constant, the energy of activation is E a (in joules), R is the reaction constant (8.314 J/mol K), T is the temperature in Kelvin and A is the frequency factor. To calculate the frequency factor A (which is sometimes called Z ), you need to know the other variables K , Ea , and T .
