Options

A. all collisions among reactant molecules having energy greater than `E_(a)` leads product formation
B. collisions among reactant molecules having energy less than `E_(a)` do not cause reaction
C. raising temperature decreases the value of `E_(a)` and thereby increases the rate of the reaction.
D. `E_(a)` is the total energy of the reacting molecules
