Elementary sulfur is often found after a volcanic eruption. The sulfur dioxide gases react with the hydrogen sulfide gases released from the eruption. 8SO2(g) + 16H2S(g) → 3S8(s) + 16H20(I) Substance AH;(kJ/mol) AG;(kJ/mol) SO-(g) H;S(g) S8(s) H2O(1) -296.4 -300.4 -20.15 -33.0 -285.8 -237.2 a. Using the thermodynamic data provided at 25.0°C determine the entropy of reaction (J/Kmol). b. Will this reaction be spontaneous at all temperatures? Explain your answer using the values calculated.
