Explanation:
The Arrhenius equation is a formula for the temperature dependence of reaction rates. This equation has a vast and important application in determining rate of chemical reactions and for calculation of energy of activation.
Arrhenius equation gives the dependence of the rate constant of a chemical reaction on the absolute temperature, a pre-exponential factor and other constants of the reaction.
k = A e − E a R T , {\displaystyle k=Ae^{\frac {-E_{\rm {a}}}{RT}},}
where:
k = rate constant,
T = absolute temperature (in kelvins),
A is the pre-exponential factor, a constant for each chemical reaction. According to collision theory, A is the frequency of collisions in the correct orientation,
Ea = activation energy for the reaction (in the same units as RT),
R = universal gas constant.
