If the initial ratio of products to reactants(the reaction quotient) is greater than the Kc then:
Correct answer: A. The reaction will shift towards the reverse direction.
- A. The reaction will shift towards the reverse direction.
- B. More quantity of products is obtained.
- C. The ratio increases to the value of Kc.
- D. Equilibrium has been attained.
- E. There is no shifting of reaction.
Explanation
If the reaction quotient Q > Kc , there are too many products compared to equilibrium. To reduce Q back to Kc , the system shifts toward reactants (reverse direction). Thus, the reaction moves backward until equilibrium is restored.

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.
