Chemistry - Thermodynamics - II Question with Solution | TestHub

For the reaction, $\mathbf{X}(s)\rightleftharpoons \mathbf{Y}(s)+\mathbf{Z}(g)$, the plot of $\ln \frac{p_{\mathbf{Z}}}{p^{\theta }}$ versus $\frac{10^4}{T}$ is given below (in solid line), where $p_{\mathbf{Z}}$ is the pressure (in bar) of the gas $\mathbf{Z}$ at temperature $T$ and $p^{\theta }=1$ bar.

(Given, $\frac{\mathrm{d}(\ln K)}{\mathrm{d}\left(\frac{1}{T}\right)}=-\frac{\Delta H^{\theta }}{R}$, where the equilibrium constant, $K=\frac{p_z}{p^{\theta }}$ and the gas constant, $\mathrm{R}=8.314\mathrm{J}{\mathrm{K}}^{-1}{\mathrm{mol}}^{-1}$ )
