Which statement correctly describes the effect of adding a catalyst to a chemical system at equilibrium, at a constant temperature?
It increases the equilibrium yield of the products.
It provides an alternative pathway with a lower activation energy for both the forward and reverse reactions.
It increases the rate of the forward reaction but has no effect on the rate of the reverse reaction.
It alters the overall enthalpy change (ΔH\Delta HΔH) of the reaction.
