Which of the following is true for a reversible reaction at equilibrium:
Correct answer: C. Rf = Rr
- A. Kf =ke
- B. [P] = [R]
- C. Rf = Rr
- D. [P] < [R]
Explanation
Rf = Rr: In a reversible reaction at equilibrium, the rates of the forward and reverse reactions are equal.

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.
