4.7: What will be the effect of temperature on rate constant?

The rate constant of a reaction is nearly doubled with a 10° rise in temperature. However,

the exact dependence of the rate of a chemical reaction on temperature is given by

Arrhenius equation,

K=Ae $^{- E a / R T}$

Where,

A is the Arrhenius factor or the frequency factor

T is the temperature

R is the gas constant

E $_{a}$ is the activation energy
