AIPMT PRELIMS 2010 Chemistry Relation between Kₚ and Kc MCQ Question
Type: MCQ-conceptual-Medium-Class 11
In which of the following reactions, Kₚ and Kc are not equal?
A
2C(s) + O₂(g) ⇌ 2CO(g)
B
2NO(g) ⇌ N₂(g) + O₂(g)
C
SO₂(g) + NO₂(g) ⇌ SO₃(g) + NO(g)
D
H₂(g) + I₂(g) ⇌ 2HI(g)
Correct Answer
Option A
Detailed Explanation
For the reaction SO₂(g) + NO₂(g) ⇌ SO₃(g) + NO(g), Δn₉ ≠ 0, hence Kₚ ≠ Kc. In other reactions, Δn₉ = 0, so Kₚ = Kc.
