All of the following are applications of K, EXCEPT:
Correct answer: C. It tells about the rate of reaction.
- A. It helps to predict the direction of the reaction.
- B. It tells about the extent of the reaction.
- C. It tells about the rate of reaction.
- D. None of these.
Explanation
The equilibrium constant (Kc ) provides information about the position of equilibrium (direction and extent) but gives no information about how fast the reaction reaches that equilibrium. The rate of reaction is the domain of chemical kinetics.

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.
