Question

Vapour density of the equilibrium mixture of the reaction

SO₂Cl₂ (g)$\rightleftarrows$SO₂ (g) + Cl₂ (g) is 50. The extent of dissociation of SO₂Cl₂ (g) is

• A. 33.33 %
• B. 35.0 %
• C. 30.0 %
• D. 66.67 %

Answer 1

Answer: (B)

35.0 %

Answer 2

50 = $\frac { ( 64 + 71 ) } { ( 1 + \alpha ) }$ = $\frac { 135 } { ( 1 + \alpha ) }$

or 1 + a = $\frac { 135 } { 2 \times 50 }$ = 1.35

a = 0.35
