The vapour density of the equilibrium mixture of the reaction:
`SO_(2)Cl_(2)(g)hArrSO_(2)(g)+Cl_(2)(g)`
is `50`. The percent dissociation of `SO_(2)Cl_(2)` is

For the reaction : 2Cl(g)-.Cl_2(g) .

At 30^(@)C, K_(p) for the dissociation reaction : SO_(2)Cl_(2)(g) hArr SO_(2)(g)+Cl_(2)(g) is 2.9xx10^(-2) atm. If the total pressure is 1 atm, the degree of dissociation of SO_(2)Cl_(2) is : (assume 1-alpha^(2)=1 ).

The volume of the reaction vessel containing an equilibrium mixture in the reaction , SO_2Cl_2(g) hArr SO_2(g) + Cl_2(g) is increased. When equilibrium is reestablished:

The volume of the reaction vessel containing an equilibrium mixture is increased in the following reaction SO_(2)Cl_(2)(g)hArrSO_(2)(g)+Cl_(2)(g) When equilibrium is re-established :
