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.
