    Chemical Thermodynamics. Asked once: 25 Jul 2022

    144
    While performing a thermodynamics experiment, a student made the following observations,
    HCl+NaOH→NaCl+H2OΔH=−57.3 kJ mol−1HCl + NaOH \rightarrow NaCl +H_{2}O\Delta H = - 57.3\text{ }kJ{\text{ }mol}^{- 1}
    CH3COOH+NaOH→CH3COONa+H2OCH_{3}COOH + NaOH \rightarrow CH_{3}COONa +H_{2}O
    ΔH=−55.3 kJ mol−1\Delta H = - 55.3\text{ }kJ{\text{ }mol}^{- 1}. The enthalpy of ionization of CH3COOHCH_{3}COOH as calculated by the student is ____\_\_\_\_ kJmol−1kJmol^{- 1}. (nearest integer)
