Choose the best answer

A catalyst is added after equilibrium is established for 2SO₂(g) + O₂(g) ⇌ 2SO₃(g). Which statement is correct?

Verified Answer & Explanation⌄

Concept Explanation

A catalyst speeds both forward and reverse reactions by lowering activation energies equally; it does not change Kc or the equilibrium position.
