By which of the following factors, equilibrium state is attained earlier?
Correct answer: D. Catalyst
- A. Temperature
- B. Pressure
- C. Concentration
- D. Catalyst
Explanation
The equilibrium state is attained earlier with a catalyst because it increases the rate of forward reaction as well as the rate of backward reaction by the same rate. Other options are not correct because they are responsible for disrupting equilibrium in one direction.

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.
