NEET Chemistry Chemical Equilibrium MCQ Question
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?
Kc = [N₂][H₂]³ / [NH₃]²
Kc = [NH₃]² / [N₂][H₂]³
Kc = [N₂][H₂] / [NH₃]
Kc = [N₂]²[H₂]³ / [NH₃]
Correct Answer
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.
