Problem: Methanol (CH3OH) has been suggested as a fuel to replace gasoline. Find ΔH˚rxn for the combustion of methanol.

FREE Expert Solution

We are asked to find ΔH˚rxn for the combustion of methanol.

The balanced combustion reaction is: 

2 CH3OH(l) + 3 O2(g) → 2 CO2(g) + 4 H2O(l)


ΔH°rxn=ΔH°f, prod-ΔH°f, react


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.
