The passage around this formula
A useful way to see why the peak exists at all is the Arrhenius picture underneath it. The observed rate constant is . 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.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
