    Heat of neutralisation of the acid-base reaction is 57.32 kJ for:

    A)  \[HN{{O}_{3}}+LiOH\]

    B)  \[HCOOH+KOH\]

    C)  \[HCl+N{{H}_{4}}OH\]

    D)  \[C{{H}_{3}}COOH+NaOH\]

    Correct Answer: A

    Solution :

    Heat of neutralisation is the heat evolved, when an acid reacts with a base. The value of heat of neutralisation of a strong acid and a strong base is always found to be constant and is equal to 57.3 kJ/mol. Here \[HN{{O}_{3}}\] is a strong acid and \[LiOH\] a strong base, hence their heat of neutralisation will be equal to 57.3 kJ/mol.
