Question
Calculate the equilibrium constant for the reaction
NiO(s) + H2(g) → Ni(s) + H2O(g)
at 1023K from the following data:
Ni(s) + ½ O2(g) → NiO(s) ΔG0 = -244,555 + 98.53 T [J]
H2(g) + ½ O2(g) → H2O(g) ΔG0 = -246,438 + 54.81 T [J]
Could a pure nickel sheet be annealed at 1023K in an atmosphere containing 95% H2O and 5% H2 by volume without oxidation?
