Apply the Arrhenius equation to rates.
The Arrhenius equation for Rate Law scales a pre-exponential factor by the exponential of the negative activation energy over the gas constant and temperature. Even a small rise in temperature raises the rate constant sharply because it sits inside an exponential.
Rate Law
k = A.exp(-Ea/RT)
k = A.exp(-Ea/RT) The Arrhenius equation for Rate Law scales a pre-exponential factor by the exponential of the negative activation energy over the gas constant and temperature.
Even a small rise in temperature raises the rate constant sharply because it sits inside an exponential.
