The passage around this formula
and a catalyst’s whole job is to substitute a smaller — 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.
