Low Activation Energy

Postby Rachel Hunsucker 3L » Thu Feb 18, 2016 9:05 pm

Can someone explain why temperature doesn't change the rate very much if a reaction has a low activation energy?

I think if the activation energy is very small, a change in temperature will only make the term (EA/RT) smaller, but since it is already very small the change is not very significant. So, when it is used in the Arrhenius equation, k=Ae^(-EA/RT), k does not change very much either, meaning the rate of the reaction does not change very much.
