Chapter 17, Problem 66E

Using data from Appendix 4, calculate ∆G for the reaction

$2{\text{H}}_2\text{S}\left(g\right)+{\text{SO}}_2\left(g\right)\rightleftharpoons 3{\text{S}}_{\text{rhombic}}\left(s\right)+2{\text{H}}_2\text{O}\left(g\right)$

for the following conditions at 25°C:

$\begin{array}{l}{P}_{{\text{H}}_{\text{2}}\text{S}}=1.0\times {10}^{-4}\text{atm}\\ P_{{\text{SO}}_{\text{2}}}=1.0\times {10}^{-2}\text{atm}\\ P_{{\text{H}}_{\text{2}}\text{O}}=3.0\times {10}^{-2}\text{atm}\end{array}$
