Question

Enthalpy of reaction for the combustion:

    C(s) + O2(g) ⟶ CO2(g)                           ΔH1 = -395.5 kJ    

    CO(g) + O2(g) ⟶ CO2(g)                     ΔH2 = -285.0 kJ

 

Using these date, calculate the enthalpy (kJ) for the combustion of C to CO:

     C(s) + O2(g) ⟶ CO(g)

Answer 1

You'll want to use Hess' Law, but your equation is incorrect as written as C(s) + O2(g) ==> CO(g). It isn't balanced. Is the question to find enthalpy for combustion to produce CO(g) or is it for the combustion to produce CO2(g)?
