asap plss thsnkassss dsadadawdafa

Given the following at 25 °C and 1.00 atm:
2Fe(s) + 02(g) → 2FEO(s)
4Fe(s) + 302(g) → 2FE2O3(s)
AH° = -544.0 kJ
AH° = -1648.8 kJ
3Fe(s) + 202(g) → Fe304(s)
AH° = -1118.4 kJ
Calculate the AH for the reaction below at 25 °C.
Fe203(s) + FeO(s) → Fe304(s)
a. -1074.0 kJ
b.249.8 kJ
C. -22.0 kJ
d. 22.2 kJ
O e. 1074.0 kJ
