234 - Figure (a) shows a mixture at equilibrium for the reaction: $2Z(g) \rightleftharpoons Y_2(g) + X_2(g)$. When equilibrium is reached, it shows the number of moles of gases $X_2$, $Y_2$, and $Z$ in figure (b), from right to left respectively, when the reaction vessel reaches equilibrium. (Each dot represents $0.1$ mol and the volume of the reaction vessel is $2.25$ liters and temperature is constant.) [Figure: Two containers showing particle distributions. Container (a) shows particles of different types. Container (b) shows: $X_2: \infty$, $Y_2: \bullet\bullet$, $Z: \bullet\bullet$]
