Dear Student,
The rate constant of a reaction is nearly doubled with a 10o rise in temperature. However, the exact dependence of the rate of a chemical reaction on temperature is given by Arrhenius equation,
k = A. e-Ea/RT
where,
A is the Arrhenius factor or the frequency factor.
T is the temperature
R in the universal gas constant
Ea is the activation energy
Hence with increase in temperature the rate constant of the reaction increases.
