Problem Details

Calculate the enthalpy change ΔH rxn for the combustion of carbon monoxide to make carbon dioxide:

          2CO + O 2 → 2CO2 

given the following bond energies:

          BE (C≡O) = 1074 kJ/mol

          BE (O=O) = 499 kJ/mol

          BE (C=O) = 802 kJ/mol 

a) +2380 kJ

b) +561 kJ

c) +1043 kJ

d) -1043 kJ

e) -561 kJ
