Problem 68

Calculate $\Delta G^{\circ}$ at 298 $\mathrm{K}$ for each reaction:
$$\begin{array}{l}{\text { (a) } 2 \mathrm{H}_{2} \mathrm{S}(g)+3 \mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{H}_{2} \mathrm{O}(g)+2 \mathrm{SO}_{2}(g)} \\ {K=6.57 \times 10^{173}} \\ {\text { (b) } \mathrm{H}_{2} \mathrm{SO}_{4}(l) \rightleftharpoons \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{SO}_{3}(g) ; K=4.46 \times 10^{-15}}\end{array}$$
