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 energy above which all the colloding molecules
B. the energy below which colloiding molecules will not react
C. the total energy of the reaction molecules at a temperature, T
D. the fraction of molecules with energy greater than the activation energy of the reaction

Answer

A

Explanation

`k=Ae^(-E_a//RT)`
`E_(a)` is activation energy. It is the energy, the molecule must have to give the product and hence above which all the colloiding molecules will react.
