All of the following are applications of Kc EXCEPT:
Correct answer: C. It tells about rate of reaction
- A. It helps to predict direction of reaction
- B. It tells about extent of reaction
- C. It tells about rate of reaction
- D. It tells about effect of change in concentration, temperature and pressure
Explanation
Kc tells us that about effect of change in concentration, temperature, pressure, extent of reaction and direction of reaction, but it does not tell about the rate of 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.
