The enthalpy change of neutralisation of a 1 M solution of \(\ce{HCl}\) with a 1 M solution of \(\ce{NaOH}\) is -57.3 kJ/mol. The enthalpy change of neutralisation of a 1 M solution of a weak acid \(\ce{HA}\) with the same \(\ce{NaOH}\) solution is -54.6 kJ/mol. If \(\ce{HA}\) is 10 percent ionized in a 1 M solution, what is the enthalpy change (in kJ/mol) for the complete dissociation of \(\ce{HA}?\)
