NEET Chemistry Chemical Equilibrium MCQ Question

Type: MCQ-numerical-Hard-Class 11

For the equilibrium reaction 2NH₃(g) ⇌ N₂(g) + 3H₂(g), if the equilibrium concentrations are [NH₃] = 0.5 M, [N₂] = 0.2 M, and [H₂] = 0.3 M, what is the correct expression for the equilibrium constant Kc?

A

Kc = [N₂][H₂]³ / [NH₃]²

B

Kc = [NH₃]² / [N₂][H₂]³

C

Kc = [N₂][H₂] / [NH₃]

D

Kc = [N₂]²[H₂]³ / [NH₃]

Correct Answer

Option A

Detailed Explanation

According to the stoichiometric coefficients in the balanced chemical equation, Kc = [N₂][H₂]³ / [NH₃]². This is based on the relationship between the stoichiometric coefficients and the equilibrium constant expression.
