$\underset { \mathbf { g } } { \mathbf { P } _ { \mathbf { 2 } } } + \underset { \mathbf { g } } { \mathbf { Q } _ { \mathbf { 2 } } } \rightleftharpoons \underset { \mathbf { g } } { 2 \mathbf { P Q } }$
2 mol each of $\mathrm { P } _ { 2 } ; \mathrm { Q } _ { 2 }$ \& PQ are at equilibrium. If 1 mol each of $\mathrm { P } _ { 2 }$ \& $\mathrm { Q } _ { 2 }$ are added at eq. Find new concentration of $\mathrm { P } _ { 2 }$ at equilibrium?\\
