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

Answer

C

Explanation

E represents the activation energy of the reaction, i.e., energy above which all the colliding molecules will react.
