WebbThe postulates of collision theory are accommodated in the Arrhenius equation. The frequency factor A is related to the rate at which collisions having the correct orientation occur. The exponential term, e − E a / R T , e − E a / R T , is related to the fraction of collisions providing adequate energy to overcome the activation barrier of the reaction.
