The chemical equation for the equilibrium is denoted by the following equilibrium constant expression:
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Option B equation matches the expression correctly. The concentrations of reactants and products in the equation correspond to the terms in the expression, including the squared concentration of NH3 and the fourth power of H2.

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.
