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 $$\ce{HA}?$$
