At equilibrium the reaction mixture contains:
Correct answer: C. Both
- A. Only Products
- B. Only Reactants
- C. Both
- D. None of these
Explanation
Option C is correct since, at equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. Hence both are present in the reaction mixture.

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.
