The enthalpies of combustion of carbon and carbon monoxide are -390 KJ

1.	The enthalpies of combustion of carbon and carbon monoxide are -390 KJ mol^(-1) and -278 KJ mol^(-1) respectively. The enthalpy of formation of carbon monoxide is
Answer» Solution :`C _("graphicle") + O _(2 (G)) to CO _(2 (g)) , DELTA H =- 393.5 kJ……..(1)` `CO _((g)) + (1)/(2) O _(2 (g)) to CO _(2 (g)) , Delta H =- 283 Kj ……..(2)` Equation (1) - equation (2) , gives `C _(("graphicle")) + (1)/(2) O _(2 (g)) to CO _((g)) ‘ Delta H =-110 .5 kJ`
