Enthalpy of neutralisation of `NaOH` with `H_(2)SO_(4)` is `-57.3kJ mol^(-1)` and with ethanoic acid `-55.2 kJ mol^(-1)`. Which of the following is the best explanation of this difference?A. Ethanoic acid is weak acid and thus requires less `NaOH` for neutralisationB. Ethanoic acid is only partly ionized, neutralisation is therefore incompleteC. Ethanoic acid is monobasic while `H_(2)SO_(4)` is dibasicD. Some heat is used to ionize the ethanoic acid completely.
