Answer #1

Combustion of C to CO2 is C(s) + O2(g) ----------------- CO2(g) $\Delta$ H = - 393.5 KJ --------- (1)

combustion of CO to CO2 is CO(g) + 1/2O2(g) ---------------- CO2(g) $\Delta$ H = - 283.0 KJ -------- (2)

The required equation is C(s) + 1/2O2(g) --------------- CO(g) $\Delta$ H = ?

(1) -------------- C(s) + O2(g) ----------------- CO2(g) $\Delta$ H = - 393.5 KJ

(2) -------------- CO(g) + 1/2O2(g) ---------------- CO2(g) $\Delta$ H = - 283.0 KJ

------------------------------------------------------------------------------------------------------------

substraction from (1) to (2) C(s) - CO(g) + 1/2O2(g) ------------------ $\Delta$ H = - 110.5 KJ

C(s) + 1/2O2(g) ---------------------- CO(g) $\Delta$ H = - 110.5 KJ

.Therefore, the enthalpy of combustion of C to CO is C(s) + 1/2O2(g) ---------------------- CO(g) $\Delta$ H = - 110.5 KJ
