Question

Assertion : If reaction quotient, $Q_c$ for a particular reaction is greater than $K_c$, the reaction will proceed in the direction of reactants.
Reason : Reaction quotient is defined in the same way as the equilibrium constant $K_c$ except that the concentrations in $Q_c$ are not necessarily equilibrium values.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

If $Q_c > K_c$, then $Q_c$ will tend to decrease so as to become $K_c$. As a result, the reaction will proceed in the backward direction.
