k=A e−Ea/RTk = A\, e^{-E_a/RT}

Why this formula appears here

A useful way to see why the peak exists at all is the Arrhenius picture underneath it. The observed rate constant is k=A e−Ea/RTk = A\, e^{-E_a/RT}. and a catalyst’s whole job is to substitute a smaller EaE_a — the barrier of the new surface-mediated path — for the barrier of the uncatalyzed reaction, without introducing a rate-limiting binding or release step that reintroduces a large barrier somewhere else in the cycle.
