Which mechanism causes a higher reaction rate with a catalyst introduced into a chemical reaction?

💡 Explanation

When a catalyst is introduced, it provides an alternative reaction pathway, lowering the required activation energy barrier because the transition state is stabilized, speeding us the reaction. Therefore, a lower activation energy occurs instead of changes to temperature, equilibrium, or concentration which would have different effects on reaction kinetics.
