Use the following thermodynamic data at 298 K to determine the equilibrium constant at this temperature for the reaction of iron in steam to form hydrogen and iron(III) oxide.
2Fe(s) + 3H2O(g) 3H2(g) + Fe2O3(s)
Substance Fe(s) H2O(g) H2(g) Fe2O3(s)
Hf (kJ/mol) 0 -242 -0 -824
Gf (kJ/mol) 0 -229 -0 -742
S(J/Kmol) 27 189 131 87

1.8 x 10-3
1.58 x 1022
4.36 x 10-9
4.36 x 109

i keep getting the wrong answer, well none of these answers, pls show working so i can figure it out myself.
