Question: Calculate Ho and So at 25oC for the reaction 2SO2 g
Calculate ΔHo and ΔSo at 25oC for the reaction 2SO2(g) + O2(g) → 2SO3(g) at a constant pressure of 1.00 atm using thermodynamic data in Appendix 4. Also calculate ΔHo and ΔSo at 227oC and 1.00 atm, assuming that the constant- pressure molar heat capacities for SO2(g), O2(g), and SO3(g) are 39.9 J K-1mol-1, 29.4 JK-1mol-1, and 50.7 J K-1mol-1, respectively. (Hint: Construct a thermodynamic cycle, and consider how enthalpy and entropy depend on temperature.)
