The heats of combustion of carbon and carbon monoxide are -393.5 and -

1.	The heats of combustion of carbon and carbon monoxide are -393.5 and -283.5 kJ "mol"^(-1), respectively. The heat of formation (in kJ) of carbon monoxide per mole is ….....
Answer» `-110.5` `110.5` `676.5` `-676.5` Solution :`C_((s))+ O_2 to CO_(2(g)) DELTAH`= -393.5 ….(1) `CO_((g)) + 1/2O_(2(g)) to CO_(2(g)) DeltaH`= - 283.5 …(2) HEAT of FORMATION of `CO_((g))` `rArr` (1)-(2) `C_((s)) + 1/2O_(2(g)) to CO_(2(g)) DeltaH`=-110.0 KJ
