Question

On heating a mixture of SO₂Cl₂ and CO two eqilibria are simultaneously established

Answer 1

The correct option is d (amount SO₂Cl₂ and CO increase)

The given equilibrium are:-

SO₂Cl₂ ⇋ SO₂ + Cl₂........(i)

CO + Cl₂ ⇋ COCl₂.........(ii)

• If more SO₂  is added at equilibrium then by Le Chatelier's principle reaction (i) will proceed backward and SO₂Cl₂ formation will be favored and Cl₂ formation is less. 
• Now, Since Cl₂ formation is reduced so in equation (ii) by Le Chatelier's principle, the reaction proceeds backward side and enhances the formation of CO.
