STANDARD Chemistry Effect of Inert Gases MCQ Question
In which of the following reactions, the equilibrium remains unaffected on addition of small amounts of argon at constant volume?
H₂(g) + I₂(g) ⇌ 2HI(g)
PCl₅(g) ⇌ PCl₃(g) + Cl₂(g)
N₂(g) + 3H₂(g) ⇌ 2 NH₃(g)
The equilibrium will remain unaffected in all the three cases.
Correct Answer
Detailed Explanation
If the volume is kept constant and an inert gas such as argon is added which does not take part in the reaction, the equilibrium remains undisturbed.
