(b) Using the bond enthalpies listed in Q1(c), and assuming all reactants and products are gases, calculate the enthalpy of combustion of ethanoic acid, noting that the bond enthalpy for C=O is +743 kJmol-1 when it is NOT in the carbon dioxide molecule.... Using the enthalpies of combustion of each of the substances involved in a reaction, found from thermodynamic tables, the enthalpy of reaction can be calculated using an imaginary cycle. Together with the absolute entropies, which may be used to obtain the entropy of reaction, again the Gibbs energy of reaction can be obtained.
