In a reversible reaction, catalyst lowers the activation energy of the:
Correct answer: C. Forward as well as reverse reaction
- A. Forward reaction
- B. Reverse reaction
- C. Forward as well as reverse reaction
- D. Forward reaction but increases that of the reverse reaction
Explanation
In the presence of a catalyst, both the forward and reverse reaction activation energy will decrease equally, thereby allowing the system to reach equilibrium faster. However, it is very important to keep in mind that the addition of a catalyst has no effect whatsoever on the final equilibrium position of the reaction.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
