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

Options

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

Answer

C

Explanation

Follow text. It is not necessary for all molecules having `E gt E_(a)` to react. They may react.
