NEET 2024 Chemistry Reaction Quotient and Equilibrium Constant MCQ Question
Type: MCQ-numerical-Medium-Class 11
For the reaction 2A ⇌ B + C, Kc = 4×10⁻³. At a given time, the composition of reaction mixture is: [A] = [B] = [C] = 2×10⁻³ M. Then, which of the following is correct?
A
Reaction has a tendency to go in backward direction.
B
Reaction has gone to completion in forward direction.
C
Reaction is at equilibrium.
D
Reaction has a tendency to go in forward direction.
Correct Answer
Option A
Detailed Explanation
The reaction quotient Q = [B][C]/[A]² = (2×10⁻³)²/(2×10⁻³)² = 1, which is greater than Kc. Thus, the reaction will shift to the left to reach equilibrium.
