A small value of Keq indicates that equilibrium occur
Correct answer: A. At a low product concentration
- A. At a low product concentration
- B. At a high product concentration
- C. After considerable time
- D. With the help of a catalyst
Explanation
The equilibrium constant (Keq) is a measure of the relative concentrations of products and reactants at equilibrium. A small value of Keq indicates that the equilibrium significantly favors the reactants, resulting in a lower concentration of products. Therefore, Option A is correct. Option B is incorrect because a high concentration of products would correspond to a large Keq. Option C is incorrect as the time factor does not influence the equilibrium constant, and Option D is incorrect because a catalyst does not affect the value of Keq, only the rate at which equilibrium is reached.

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.
