Arrhenius equation is

A

a high activation energy usually implies a fast reaction.

B

ate constant increases with increase in temperature. This is due to a greater number of collisions whose energy exceeds the activation energy.

C

higher the magnitude of activation energy, stronger is the temperature dependence of the rate constant.

D

the pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their energy.
