For the reaction N_2(g) + 3 H_2(g) rightarrow 2 NH_3(g) Delta G degree = -23.6 kJ and Delta S degree = -198.7 J/K at 345 K and 1 atm. This reaction is (reactant, product) favored under standard conditions at 345 K. The standard enthalpy change for the reaction of 2.30 moles of N_2(g) at this temperature would be kJ. For the reaction 2 H_2O_2(l) rightarrow 2 H_2O(l) + O_2(g) Delta G degree = -236.9 kJ and Delta H degree = -196.00 kJ at 325 K and 1 atm. This reaction is (reactant, product) favored under standard conditions at 325 K. The entropy change for the reaction of 1.57 moles of H_2O_2(l) at this temperature would be J/L. For the reaction Fe_2O_3(s) + 3H_2(g) rightarrow 2Fe(s) + 3H_2O(g) Delta H degree = 98.8 kJ and Delta S degree = 142.5 J/K The standard free energy change for the reaction of 2.35 moles of Fe_2O_3(s) at 281 K, 1 atm would be kJ. This reaction is (reactant, product) favored under standard conditions at 281 K. Assume that Delta H degree and Delta S degree are independent of temperature.
