Fe3O4(s) + 4H2(g)3Fe(s) + 4H2O(g)
HÂ° = 151.2 kJ and SÂ° = 169.4 J/K
The standard free energy change for the reaction of 1.89 moles of Fe3O4(s) at 346K, 1 atm would be kJ.
This reaction is (reactant, product) favored under standard conditions at 346 K.
Assume that HÂ° and SÂ° are independent of temperature.
