Ethanoic acid and hydrochloric acid react with sodium hydroxide solution. The enthalpy of neutralisation of ethanoic acid is -55.8kj/mol while that of hydrochloric acid is -57.3kj/mol. Can you think of the difference?

Explanation:
Enthalpy changes of neutralisation are always negative - heat is given out when an acid and and alkali react. For reactions involving strong acids and alkalis, the values are always very closely similar, with values between -57 and -58 kJ mol-1.
That varies slightly depending on the acid-alkali combination (and also on what source you look it up in!).
