Which of the following best explains the effects of a catalyst on the rate of a reversible reaction? (a) It decreases the rate of the reverse reaction (b) It increases the kinetic energy of the reacting mol ecules (c) It moves the equilibrium position to the right (d) It provides a new reaction path with a lower activation energy

The activation energy of an uncatalyzed reaction is 95 $\mathrm{kJ} / \mathrm{mol} .$ The addition of a catalyst lowers the activation energy to 55 $\mathrm{kJ} / \mathrm{mol}$ . Assuming that the collision factor remains the same, by what factor will the catalyst increase the rate of the reaction at (a) $25^{\circ} \mathrm{C},$ (b) $125^{\circ} \mathrm{C} ?$
