Consider the following gaseous equilibrium in a closed container of volume $V$ at temperature $T$:

$P_2(\text{g}) + Q_2(\text{g}) \rightleftharpoons 2PQ(\text{g})$

Initially, $2$ moles each of $P_2(\text{g})$, $Q_2(\text{g})$ and $PQ(\text{g})$ are present at equilibrium. One mole each of $P_2$ and $Q_2$ are added. The number of moles of $P_2$, $Q_2$ and $PQ$ at the new equilibrium respectively are
