Solution
The correct option is D All are incorrect At constant volume, there is no effect of addition of inert gas to a reaction in equilibrium. At constant pressure, for the reactions for which Δn=0. there is no effect of addition of inert gas to a reaction in equilibrium. At constant pressure, for the reactions for which Δn≠0, the equilibrium shifts in the direction of more number of moles.
