Question

For the reaction $$ \mathrm{CH}_{3} \mathrm{OH}(\ell)+\frac{3}{2} \mathrm{O}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}(\ell)+\mathrm{CO}_{2}(\mathrm{~g}) $$ the value of $\Delta G^{\circ}$ is $-702.35 \mathrm{~kJ}$ at $25^{\circ} \mathrm{C}$. Other data at $25^{\circ} \mathrm{C}$ are Calculate the standard molar entropy, $S^{\circ}$, for $\mathrm{O}_{2}(\mathrm{~g})$.

          For the reaction
$$
\mathrm{CH}_{3} \mathrm{OH}(\ell)+\frac{3}{2} \mathrm{O}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}(\ell)+\mathrm{CO}_{2}(\mathrm{~g})
$$
the value of $\Delta G^{\circ}$ is $-702.35 \mathrm{~kJ}$ at $25^{\circ} \mathrm{C}$. Other data at $25^{\circ} \mathrm{C}$ are
