We are asked to calculate the molar enthalpy of combustion to CO2 (g) and H2O(l) for n-Butane.
Note that we need to multiply each ΔH˚f by the stoichiometric coefficient since ΔH˚f is in kJ/mol.
Also, note that ΔH˚f for elements in their standard state is 0.
C4H10(g) + 13/2 O2(g)→ 4 CO2(g) + 5 H2O(g)
|1,3-Butadiene||C4 H6 (g)||111.9|
|1-Butene||C4 H8 (g)||1.2|
|n-Butane||C4 H10 (g)||-124.7|
For n-Butane calculate the molar enthalpy of combustion to CO2 (g) and H2 O(l).
