NEET 2024 Chemistry Relation between Kp and Kc MCQ Question
Type: MCQ-conceptual-Medium-Class 11
In which of the following equilibria, Kp and Kc are NOT equal?
A
CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)
B
2 BrCl(g) ⇌ Br₂(g) + Cl₂(g)
C
PCl₅(g) ⇌ PCl₃(g) + Cl₂(g)
D
H₂(g) + I₂(g) ⇌ 2 HI(g)
Correct Answer
Option C
Detailed Explanation
For reactions involving gases, Kp = Kc(RT)^(Δn), where Δn is the change in moles of gas. In option C, Δn = 1, so Kp ≠ Kc.
