Which mechanism reduces activation energy when vanadium(V) oxide catalyst converts sulfur dioxide to sulfur trioxide?

💡 Explanation

When vanadium(V) oxide catalyzes sulfur dioxide oxidation, it provides an alternative reaction pathway because it forms intermediate compounds with the reactants, lowering the activation energy and increasing the reaction rate. Therefore, the reaction proceeds via an alternate pathway, rather than solely by increasing collision frequency, raising temperature, or lowering pressure, which relies on differing kinetic/thermodynamic principles.Catalyst stabilizes transition state.
