Chemical equilibrium is established in:
Correct answer: A. Reversible reaction
- A. Reversible reaction
- B. Irreversible reaction
- C. Both A and B
- D. Forward reaction
Explanation
Chemical equilibrium is a state that is reached only in reversible reactions. It is the point at which the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in concentrations.

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.
