heat of reaction for the oxidation of iron......?

Question

Determine the heat of reaction for the oxidation of iron,
4 Fe(s) + 3 O2(g) → 2 Fe2O3(s)
given the thermochemical equations below.

2 Fe(s) + 6 H2O(λ) → 2 Fe(OH)3(s) + 3 H2(g) ΔH = +321.8 kJ
2 H2O(λ) → 2 H2(g) + O2(g) ΔH = +571.7 kJ
Fe2O3(s) + 3 H2O(λ) → 2 Fe(OH)3(s) ΔH = +288.6 kJ

a.-505.3 kJ
b.+360.5 kJ
c.-1182.1 kJ
d.+1447.1 kJ
e.-1648.7 kJ

Answer 1

e.-1648.7 kJ
