Question

When wine goes bad, the ethanol (C2H5OH) is converted to acetic acid (HC2H3O2) in the following reaction: C2H5OH(l)+O2(g)→HC2H3O2(l)+H2O(l) However, this is usually a slow reaction, and when doing it in a calorimeter, the reaction goes to complete oxidation, giving the heats of reaction listed below: C2H5OH(l)+3O2(g)→2CO2(g)+3H2O(l),HC2H3O2(l)+2O2(g)→2CO2(g)+2H2O(l),ΔH∘=1410 kJ/molΔH∘=874 kJ/mol Part B Determine the heat of the reaction (ΔH) for the conversion of ethanol to acetic acid.
