7. (16 pts) Consider the following decomposition reaction: FeO(s)+CO(g)Fe(s)+CO2(g) a) Calculate G for this reaction at 298K. At 298K, the Gf for FeO(s) is 251kJ/mol, the Gf for CO(g) is 137kJ/mol, and the G for CO2(g) is 394kJ/mol. b) Calculate H(298K) for the reaction given above, using the following reactions and d) At what temperatures is this reaction spontaneous at standard conditions? Assume that H and S do not depend on temperature
