On combustion, carbon forms two oxides CO and CO_(2), Heat of formatio – InterviewSolution

1.	On combustion, carbon forms two oxides CO and CO_(2), Heat of formation of CO_(2) gas is 94.3 kcal and that of CO is 26.0 kcal. Heat of combustion of carbon is
Answer» 26.0 kcal `- 94.3` kcal 68.3 kcal `- 120.3` kcal Solution :`C+O_(2)rarrCO_(2),DeltaH=-94.3` This is ALSO heat of FORMATION of `CO_(2)` `C+(1)/(2)O_(2)rarrCO, DeltaH=-26.0`.
