Thermodynamics

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R)

Assertion (A) : Enthalpy of neutralisation of strong monobasic acid with strong monoacidic base is always \(-57 \mathrm{~kJ} \mathrm{~mol}^{-1}\)

Reason (R) : Enthalpy of neutralisation is the amount of heat liberated when one mole of \(\mathrm{H}^{+}\) ions furnished by acid combine with one mole of \({ }^{-} \mathrm{OH}\) ions furnished by base to form one mole of water.

In the light of the above statements, choose the correct answer from the options given below.
