For the reaction Fe2O3(s) + 3H2(g)2Fe(s) + 3H2O(g) H°rxn = 98.8 kJ and S°rxn = 142.5 J/K The standard free energy change for the reaction of 2.47 moles of Fe2O3(s) at 267 K, 1 atm would be kJ. This reaction is (reactant, product) favored under standard conditions at 267 K. Assume that H°rxn and S°rxn are independent of temperature.
