According to collision theory of reaction rates, the rate of reaction depends

Collision theory can be mathematically stated as x a E RT k Z Ae Where, Z ->Related to orientation A ->Frequency of collision a E RT e ->Fraction of effective collision Combining a E RT A e x gives frequency of effective collision. Thus, rate depends on frequency of effective collision & orientation of molecules at time of collision. Fraction of molecules with energy E Energy 1T 2T 2 1 T >T a E a -E RT e
