Question

What happens when a catalyst is added to a system at equilibrium? *
(a) The reaction follows an alternative pathway of lower activation energy.
(b) The heat of reaction decreases.
(c) The potential energy of the reactants decreases.
(d) The potential energy of the products decreases.​

Answer 1

Answer:

The addition of a catalyst to a reaction at equilibrium makes the reaction to follow an alternative pathway that have a lower activation energy. The catalyst makes the reaction to follow that pathway in which the energy barrier is less. Due to this, the reaction occurs at a faster rate. Hence, the correct option is (a).
