The velocity constants for the forward and backward reactions are 3.6 × 10⁻⁴ and 1.2 × 10⁻⁵. The equilibrium constant of the reaction is:
Correct answer: D. 30
- A. 3
- B. 0.033
- C. 0.33
- D. 30
Explanation
Equilibrium constant = rate of forward reaction / rate of reverse 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.
