Could you please assist me with my homework problem?
3Fe2O3 + CO a)-109 kJ b) +40.5 kJ c) -15.5 kJ d) -59.0 kJ e) +109 kJ ->> CO2 + 2Fe304
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
