the first photo is the typed out information from appendix 2 to help answer the following question
Assuming that neither standard enthalpy changes of formations (AHo) f nor standard molar entropies (So) depend upon temperature, estimate using the Table of Thermodynamic Data in Appendix 2: (a) the standard Gibbs free energy change for the reaction that forms rhombic sulfur at 600 K, and (b) the temperature (in oC) at which reaction will stop formation of products: 2H2S(g) + SO2(g) → 3S(rhombic, s) + 2H2O(g) Round off your answers to the nearest integer. Report the temperature in oC. H2S(g) has -20.15 kj/mol Delta Hf, -33.0 kj/mol Delta Gf, and 205.64 (j/k*mol) S SO2 has -296.4 kj/mol Delta Hf, -300.4 kj/mol Delta Gf, and 248.5 (j/k*mol) S S(rhombic, s) has 0 Delta Hf, 0 Delta Gf, and 31.88 (j*k/mol) S H2O(g) has -241.8 (kj/mol) Delta Hf, -228.6 Delta Gf, and 188.7 (j/k*mol) S
