The given reversible gaseous reaction :
2X2Y(g) ⇌ 2X2(g) + Y2(g)
Where
Volume of the vessel being 1 L
the concentrations of the reactants and products at equilibrium will be as follows
[X2Y(g)]=(1−α)M
[X2(g)]=αM
[Y2(g)]=α2M
Now concentration equilibrium constant
Kc=[X2(g)]2[Y2(g)][X2Y(g)]2
⇒8⋅10−6=(α)2⋅α2(1−α)2 Neglecting
α comparing with 1
⇒α32=8⋅10−6
So the percent dissociation
