Which of the following gives the temperature dependence of a reaction?

Arrhenius equation

The temperature dependence of the rate of a chemical reaction can be accurately explained by Arrhenius equation.

k = Ae^-E_a/RT 

where A is the Arrhenius factor or the frequency factor. It is also called pre-exponential factor. It is a constant specific to a particular reaction. R is gas constant and E_a is activation energy measured in joules/mole (J mol^–1).
