For the reaction 2A ⇌ B + C, Kc = 4×10⁻³. At a given time, [A] = [B] = [C] = 2×10⁻³ M. Which of the following is correct?

Options

1. Forward direction
2. Backward direction
3. Gone to completion
4. At equilibrium

Correct Answer

Reaction has a tendency to go in forward direction

Explanation

Qc = ([B][C])/([A]²) = (2×10⁻³ × 2×10⁻³)/(2×10⁻³)² = 1; since Qc < Kc, reaction proceeds forward.
