Chapter 18, Problem 18.94SP

Use the data in Appendix B to calculate $\Delta {\text{H}}^{\text{o}}$ and $\Delta {\text{S}}^{\text{o}}$ for each of the following reactions. From the values of $\Delta {\text{H}}^{\text{o}}$ and $\Delta {\text{S}}^{\text{o}}$ , calculate $\Delta {\text{G}}^{\text{o}}$ at 25 °C, and predict whether each reaction is spontaneous under standard-state conditions.
(a) ${\text{N}}_{\text{2}}\left(\text{g}\right){\text{ + 2 O}}_{\text{2}}\left(\text{g}\right)\to {\text{ 2 NO}}_{\text{2}}\left(\text{g}\right)$
(b) ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{OH(l)+O}}_{\text{2}}(g)\to {\text{CH3CO2H(l)+H}}_{\text{2}}\text{O(l)}$
