In the following reaction, 3A (g)+B(g) hArr 2C(g) +D(g) , Initial moles of B is double at A . At equilibrium, moles of A and C are equal. Hence % dissociation is :

For the dissociation of NH_(3)(g) as 2NH_(3)(g)iffN_(2)(g)+3H_(2)(g) , the variation of (1 + alpha) against ((D)/(d)) is represented as : (Given : D = initial vapour density of PCl_(5) , d = Vapour density of mixture at equilibriu,):

Assertion : For the reaction : A(g) +B(g) hArr C (g) +D (g) at a given temperature , there will be no effect of the addition inert gas at constant pressure or at constant volume. Reason : For the reaction Delta^(n) =0. Therefore there is no effect of addition of inert gas either at constant volume or at constant pressure.
