Which of the following statements describes a reversible reaction:
Correct answer: C. Both forward and reverse reaction occur simultaneously at the same time under same conditions.
- A. Both forward and reverse reaction do not occur simultaneously
- B. Both forward and reverse reaction occur simultaneously but under different conditions
- C. Both forward and reverse reaction occur simultaneously at the same time under same conditions.
- D. Forward and reverse reaction takes place at different time and different conditions
Explanation
In dynamic equilibrium, both forward and reverse reaction takes place simultaneously because conditions applied favour both the forward and reverse reactions.

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.
