हिन्दीFor the reaction \( 2A \rightleftharpoons B + C \), \( K_c = 4 \times 10^{-3} \). At a given time, the composition of reaction mixture is: \( [A] = [B] = [C] = 2 \times 10^{-3}\text{ M} \). Then, which of the following is correct?
View Answer & Solution
Correct answer · Option A
Reaction has a tendency to go in backward direction.
Explanation
The reaction quotient \( Q_c = \frac{[B][C]}{[A]^2} = \frac{(2 \times 10^{-3})(2 \times 10^{-3})}{(2 \times 10^{-3})^2} = 1 \). Since \( Q_c > K_c \) (\( 1 > 4 \times 10^{-3} \)), the reaction has a tendency to go in the backward direction.
