Answer 1

The correct option is A 1
The heat of neutralization of strong acids and strong bases is always equal to 13.7 kcal/mol or 57.3 kJ/mol. It is independent of the nature of strong acid or strong base. It corresponds to the reaction $H^{+}+O{H}^{-}\to H_{2}O$ It is equal to the heat of formation of water.
