Transcribed Image Text:6. Find AH for the following reaction:
Fe2O3 (s) + 3 CO (g) → 2 Fe (s) + 3 CO₂ (g)
Use these reactions and AH's:
4 Fe (s) + 3 O₂ (g) → 2 Fe₂O3 (s)
CO (g) + O2 (g) → CO₂ (g)
AH= -1648 kJ
ΔΗ= -283 kJ
7. Find AH for the following reaction:
C6H12O6 (s) 2 C₂H5OH (l) + 2 CO2 (g)
The standard enthalpies of formation are:
6 C (s) + 6 H₂(g) + 3 O2(g) → C6H12O6 (S)
2 C(s) + 3 H₂(g) + O2(g) → C₂H5OH (l)
C(s) + O₂ (g) → CO₂ (g)
