Select all that apply. The catalyzed reaction will reach equilibrium faster than the uncatalyzed reaction. The uncatalyzed reaction will reach equilibrium faster than the catalyzed reaction. The equilibrium position of the catalyzed reaction is greater than that of Reaction 1. The equilibrium position is the same in both the catalyzed reaction and the uncatalyzed reaction. The equilibrium position of the catalyzed reaction is shifted toward the products side. The equilibrium position of the catalyzed reaction is shifted toward the reactants side.
