14. Carbon, oxygen and water can combined to produce formic acid. Using Hess'
law and the three thermochemical equations, calculate the AH of reaction for this
reaction (10 points)
2C(s) + O2(g) + 2H2O(l) → 2 H2CO2(e)
AH =
Data
C(s) + 12 O2(g) → CO(9)
AH rxn = -110.5 kJ
H2CO2(0) H2CO2(g)
AH rxn = +62.9 kJ
CO(g) + H2O() → H2CO2(g)
AH rxn = +33.7 kJ
