The passage around this formula
A catalyst does its work by opening a lower-energy pathway between reactants and products — typically by binding an intermediate, weakening a bond that would otherwise need more thermal energy to break, and then releasing the product so the surface is free for another cycle. The energetics of that binding step follow a well-established shape: bind too weakly and the reactant never activates; bind too strongly and the product never leaves. Plotted against binding energy, catalytic activity for a given reaction traces an inverted-U — the Sabatier principle — and the best catalysts sit as close as possible to the peak. Here the activation energy is itself a function of the binding energy…

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.
