NEET Chemistry Chemical Equilibrium MCQ Question
Consider a hypothetical diagram showing a gaseous equilibrium system: A closed container with gases NO, O2, and NO2 at equilibrium. Based on the reaction NO (g) + ½ O2 (g) ⇌ NO2 (g), which label best represents the equilibrium expression Kc for this system?
Kc = [NO2] / ([NO][O2]^0.5)
Kc = [NO]^0.5 / ([NO2][O2])
Kc = [NO2]^0.5 / ([NO][O2])
Kc = [NO][O2] / [NO2]
Correct Answer
Detailed Explanation
The equilibrium expression for the reaction NO (g) + ½ O2 (g) ⇌ NO2 (g) is Kc = [NO2] / ([NO][O2]^0.5), reflecting the stoichiometry of the balanced chemical equation.
