How can the standard enthalpy of formation of CO(g) be calculated from the stand

Question

How can the standard enthalpy of formation of CO(g) be calculated from the standard enthalpy of formation Delta H3f of CO2(g) and the standard heat of combustion Delta Hccomb of CO(g)? Delta H degree f, CO = Delta H degree , CO2 + Delta H degree omb, CO Delta H degree O = Delta H degree , CO2 - Delta H degree omb, CO Delta H degree , CO = Delta H degree omb, CO - Delta H degree , CO2 Delta H degree , CO = Delta H degree omb, CO - 2 Delta H degree CO2 Delta H degree CO = 2 [Delta H degree omb CO - Delta H degree , CO2]

Explanation / Answer

CO + 1/2 O2 = CO2 Hcomb, CO (1)

C + O2 = CO2   Hf,CO2 (2)

(2) - (1) = HF,CO

OPTION 2 IS CORRECT
