Rate of reaction can be expressed by Arrhenius equation as `k =Ae^( - E_(a ) // RT)`. In this equation, `E_a` represents

Options

A. the energy below which colliding molecules will not react
B. the energy above which all the colliding molecules will react
C. the fraction of molecules with energy greater than the activation energy of the reaction.
D. the total energy of the reacting molecules at the temperature (T)

Explanation

The energy needed to form the activated complex is known as activation energy. It is the energy contained by reactant molecules that results into effective collision between them to form products.
