At the sublimation temperature, for the process ${\mathrm{CO}}_2\left(\mathrm{s}\right)\to {\mathrm{CO}}_2\left(\mathrm{g}\right)$,

The value of ${\log }_{10}$$\mathrm{K}$ for a reaction$\mathrm{A} \rightleftharpoons \mathrm{B} \mathrm{is}$

$$\begin{gathered} (\mathrm{Given}:{∆}_{\mathrm{r} }\mathrm{H}{°}_{298 \mathrm{k}}=-54.07 \mathrm{kJ} {\mathrm{mol}}^{-1,} \\ {∆}_{\mathrm{r}}\mathrm{S}{°}_{298 \mathrm{k}}=10 \mathrm{J} {\mathrm{K}}^{-1} {\mathrm{mol}}^{-1}\mathrm{and} \\ \mathrm{R}=8.314 \mathrm{J} {\mathrm{K}}^{-1} {\mathrm{mol}}^{-1}; \\ 2.303\times 8.314\times 298=5705) \end{gathered}$$
