AIPMT PRELIMS 2008 Chemistry Equilibrium Constants MCQ Question
Type: MCQ-numerical-Hard-Class 11
The value of equilibrium constant of the reaction, HI(g) ⇌ 1/2 H₂(g) + 1/2I₂(g) is 8.0. The equilibrium constant of the reaction, H₂(g) + I₂(g) ⇌ 2HI(g) will be -
A
16
B
1/8
C
1/16
D
1/64
Correct Answer
Option D
Detailed Explanation
The equilibrium constant for the reverse reaction is the reciprocal of the given reaction. Since the reaction is reversed and doubled, K = (1/8.0)² = 16.
