Above what temperature does the following reaction become nonspontaneous? 2 H2S(g) + 3 O2(g) → 2 SO2(g) + 2 H2O(g) ÄH = -1036 kJ; ÄS = -153.2 J/K

Use Hess’s law to calculate ÄG°rxn using the following information. NO(g) + O(g) → NO2(g) ÄG°rxn = ? 2 O3(g) → 3 O2(g) ÄG°rxn = +489.6 kJ O2(g) → 2 O(g) ÄG°rxn = +463.4 kJ NO(g) + O3(g) → NO2(g) + O2(g) ÄG°rxn = – 199.5 kJ
