Vedclass · Answer

(A) For a gaseous reaction,the effect of volume change on the equilibrium position depends on the change in the total number of moles of gaseous species,denoted as $\Delta n_g$.
If $\Delta n_g = 0$,the equilibrium is not affected by a change in volume or pressure.
In the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2NO_{(g)}$,the number of moles of gaseous reactants is $1 + 1 = 2$ and the number of moles of gaseous products is $2$.
Since $\Delta n_g = 2 - 2 = 0$,a change in the volume of the system does not alter the number of moles at equilibrium.

In which of the following equilibria does a change in the volume of the system not alter the number of moles?
