Question

in the arrhenius equation,what does the factor e^-ea/rt corresponds to

Answer 1

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 2

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
