The reaction SO2(g)+NO2(g)→SO3(g)+NO(g)\text{SO}_2(g)+\text{NO}_2(g)\rightarrow \text{SO}_3(g)+\text{NO}(g) is studied in a sealed container at constant temperature. In a second trial, a small amount of NO(g)\text{NO}(g) is added as a catalyst and is regenerated during the reaction. The overall reactants and products remain the same, and the catalyst is not consumed. Which statement best explains the increased rate in the presence of the catalyst?
