Question
The enthalpies of combustion of carbon and carbon monoxide are -393.5 and -283 kJ mol-1 respectively. The enthalpy of formation of carbon monoxide per mole is
-
110.5 kJ
-
-110.5 kJ
-
-676.5 kJ
-
676.5 kJ
Solution
B.
-110.5 kJ
This equation (III) also represents formation of ore mole of CO and thus enthalpy change is the heat formation of CO (g)
