AIPMT PRELIMS 2008 Chemistry Dissociation Equilibrium MCQ Question
Type: MCQ-numerical-Hard-Class 11
The dissociation equilibrium of a gas AB₂ can be represented as : 2AB₂(g) ⇌ 2AB(g) + B₂(g) The degree of dissociation is 'x' and is small compared to 1. The expression relating the degree of dissociation (x) with equilibrium constant Kₚ and total pressure P is -
A
(2Kₚ/P)¹/²
B
(Kₚ/P)
C
(2Kₚ/P)
D
(2Kₚ/P)¹/³
Correct Answer
Option C
Detailed Explanation
The expression for degree of dissociation is derived from the equilibrium constant expression considering the stoichiometry of the reaction.
