Transcribed Image Text:3Fe2O3 + CO a)-109 kJ b) +40.5 kJ c) -15.5 kJ d) -59.0 kJ e) +109 kJ ->> CO2 + 2Fe304
Consider the following thermochemical equations:
Fe₂O3 + 3CO → 2Fe +3CO₂
3Fe + 4CO₂ → 4CO + Fe3O4
Calculate the value of AH° (in kJ) for :
3Fe2O3 + CO
CO2 + 2Fe3O4
O
a)-109 kJ
b) +40.5 kJ
c) -15.5 kJ
→
AH = -28.0 kJ
AH = +12.5 kJ
