While performing a thermodynamics experiment, a student made the following observations,
\( \mathrm{HCl}+\mathrm{NaOH} \longrightarrow \mathrm{NaCl}+\mathrm{H}_{2} \mathrm{O}, \Delta \mathrm{H}=-57.3 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
\( \mathrm{CH}_{3} \mathrm{COOH}+\mathrm{NaOH} \rightarrow \mathrm{CH}_{3} \mathrm{COONa}+\mathrm{H}_{2} \mathrm{O} \)
\( \Delta \mathrm{H}=-55.3 \mathrm{~kJ} \mathrm{~mol}^{-1} \).
The enthalpy of ionization of \( \mathrm{CH}_{3} \mathrm{COOH} \) as calculated by the student is \( \mathrm{kJ} \mathrm{mol}^{-1} \).
