Step 1
5 kJ/mol. This can be thought of as two steps: C to CO and then CO to CO2. Second, we know that the combustion of CO to CO2 is -283.0 kJ/mol. We want to find the enthalpy for the combustion of C to CO. This is the first step in the combustion of C to CO2. Show more…

The enthalpy of combustion of solid carbon to form carbon dioxide is $-393.7 \mathrm{~kJ} / \mathrm{mol}$ carbon, and the enthalpy of combustion of carbon monoxide to form carbon dioxide is $-283.3 \mathrm{~kJ} / \mathrm{mol} \mathrm{CO}$. Use these data to calculate $\Delta H$ for the reaction $$ 2 \mathrm{C}(s)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{CO}(g) $$
The enthalpy of reaction for the combustion of C to CO2 is -393.5 kJ/mol of C, and the enthalpy for the combustion of CO to CO2 is -566.0 kJ/mol : C(s) + O2(g) → CO2(g) ΔH1 = -393.5 kJ 2 CO(g) + O2(g) → 2 CO2(g) ΔH2 = -566.0 kJ Using these data, calculate the enthalpy (kJ) for the combustion of C to CO: Do not include the units in your answer but do include the correct sign before your numerical value. C(s) + 1/2 O2(g) → CO(g) ΔH3 = ?
