Question

For the reaction, $X_{(s)} ightleftharpoons Y_{(s)}+Z_{(g)}$, the plot of $\ln \frac{p_Z}{p^{\circ}}$ versus $\frac{10^4}{T}$ is given below (in solid line), where $p_Z$ is the pressure (in bar) of the gas $Z$ at temperature $T$ and $p^{\circ}=1$ bar.
\ (Given: $\frac{d(\ln K)}{d(1 / T)}=-\frac{\Delta H^{\circ}}{R}$, where the equilibrium constant, $K=\frac{p_Z}{p^{\circ}}$ and the gas constant, $R=8.314 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ )
