NEET 2017 Chemistry Le Chatelier's Principle MCQ Question
Type: MCQ-numerical-Hard-Class 11
A 20 litre container at 400 K contains CO₂(g) at pressure 0.4 atm and an excess of SrO (neglect the volume of solid SrO). The volume of the container is now decreased by moving the movable piston fitted in the container. The maximum volume of the container, when pressure of CO₂ attains its maximum value, will be
(Given that: SrCO₃(s) ⇌ SrO(s) + CO₂(g), Kₚ = 1.6 atm)
A
5 litre
B
10 litre
C
4 litre
D
2 litre
Correct Answer
Option A
Detailed Explanation
Using the equilibrium constant expression and the initial conditions, the maximum volume is calculated to be 4 litres when the pressure of CO₂ is maximized.
