in this equation Ea is the activation energy
                          R is the universal gas constant
                          T is the temperature and
                          A is the arrhenius constant

Answer: Boltzmann factor

Explanation: The effect of temperature on rate constant is given by Arrhenius equation:

k=Ae^{\frac{-E_a}{RT}

k= rate constant

E_a= activation energy

R= gas constant

T= temperature

where, A= pre exponential factor and is called as frequency factor as it gives the frequency of collisions of the reacting molecules per second per liter.

e^{\frac{-E_a}{RT}=\frac{N_E}{N_T}= Boltzmann factor which gives the fraction of molecules having energy equal to or greater than the activation energy.

where N_E= number of molecules having energy equal to or graeater than activation energy

N_T= Total number of molecules
