The frequency factor from the calculation is 7.1 × 10^25.
The Arrhenius theory holds that the reaction between molecules owes to the collision between the reactant species. The reacting molecules must posses energy in excess of a minimum amount called the activation energy.
From the theory;
k = A e^-Ea/RT
k = rate constant
A = collision factor
Ea = activation energy
R = gas constant
T = Absolute temperature
5.8 × 10–6 = Ae^-(265 × 10^3/8.314 × 460)
A = 5.8 × 10^–6/8.1 × 10^-31
A = 7.1 × 10^25
