NEET 2026 Chemistry Relation between Kₚ and Kc MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Given below are certain reactions. Identify the reaction for which Kₚ ≠ Kc.
A
H₂O(g) + CO(g) ⇌ H₂(g) + CO₂(g)
B
N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
C
H₂(g) + I₂(g) ⇌ 2HI(g)
D
N₂(g) + O₂(g) ⇌ 2NO(g)
Correct Answer
Option 1
Detailed Explanation
For Kₚ = Kc, Δng = 0. In reaction (1), Δng = 0, so Kₚ ≠ Kc. In other reactions, Δng = 0, so Kₚ = Kc.
