What is Meant by the Arrhenius Equation?

In Chemistry, the Arrhenius equation is an equation which provides the relationship between temperature, rate constant and the activation energy. The Arrhenius equation is mostly used to find the rate and activation energy of the chemical reaction. The formula to calculate the temperature dependence rate constant using the Arrhenius equation is given by

K = Ae (-Ea/RT)

Where

A is the pre-exponential factor

Ea is the activation energy

T is the absolute temperature

R is the universal gas constant

K is the rate constant.
