Consider the following gaseous equilibrium in a closed container of volume ' V ' at T(K). $$\mathrm{P}_2(\mathrm{~g})+\mathrm{Q}_2(\mathrm{~g}) \rightleftharpoons 2 \mathrm{PQ}(\mathrm{~g}) $$ $\displaystyle 2$ moles each of $\displaystyle \mathrm{P}_2(\mathrm{~g}), \mathrm{Q}_2(\mathrm{~g})$ and $\displaystyle \mathrm{PQ}(\mathrm{g})$ are present at equilibrium. Now one mole each of ' $\displaystyle \mathrm{P}_2$ ' and ' $\displaystyle \mathrm{Q}_2$ ' are added to the equilibrium keeping the temperature at $\displaystyle \mathrm{T}(\mathrm{K})$. The number of moles of $\displaystyle \mathrm{P}_2, \mathrm{Q}_2$ and PQ at the new equilibrium, respectively, are
