Answer:
Explanation:
From the combustion of carbon, the reactions occurring in limited oxygen conditions are:
If it occurs in excess, then any leftover CO changes to CO2. i.e.
---- (1)
----- (2)
From (1), the enthalpy change is:
From (2), the enthalpy change is:
Subtracting (2) from (1), we get:
<u> </u>
The enthalpy change ΔH of the reaction = -110.5 kJ/mol
