Answer

Please see the work below.

Work Step by Step

We know that all neutralizations which involves strong acid and base evolve 55.09 KJ of heat per mole of $H_3O^+$. Hence, the thermochemical evidence for the Arrhenius concept is based on the fact that when 1 mole of any strong acid is neutralized by 1 mole of any strong base, the heat of neturalization is always the same.
