Question

The equilibrium, SO₂Cl₂ (g)$\rightleftarrows$SO₂ (g) + Cl₂ (g) is attained at 298 K in a closed container and an inert gas, He is introduced. Which of the following is/are correct ?

• A. Concentration of SO₂ (g), Cl₂ (g) and SO₂ Cl₂ (g) remain unchanged
• B. More Cl₂ (g) is formed
• C. Concentration of SO₂ (g) is reduced
• D. More SO₂Cl₂ (g) is formed

Answer 1

Answer: (A)

Concentration of SO₂ (g), Cl₂ (g) and SO₂ Cl₂ (g) remain unchanged

Answer 2

At constant volume, is constant, therefore due to

introduction of inert gas equilibrium remain unaffected.
