## Arrhenius equation

A relation used to describe the temperature dependence of the rate coefficient for a chemical reaction.

The form of the equation is where

*k*is the rate coefficient,*A*is the preexponential factor,*E*_{a}is the activation energy for the reaction,*R*is the gas constant, and*T*is the absolute temperature.
