B
If molecules are moving fast enough, the collisions will result in kinetic energy that can be used to bend, stretch, and eventually break the bonds of the reactants releasing the potential energy in a usable form.

C
All reactions eventually form an intermediate that lowers the overall energy requirements of the reaction resulting in a relatively reasonable activation energy.

Solution

The correct option is A The value of activation energy varies from reaction to reaction.
The rate of the reaction increases when the temperature increases because the kinetic energy of molecules increases with increasing temperature. As a result, more molecular collisions occur with energy equal to or greater than the activation energy.
The value of activation energy varies from reaction to reaction.
