MCQ
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 $-57 kJ mol ^{-1}$
Reason (R): Enthalpy of neutralisation is the $H ^{+}$ amount of heat liberated when one mole of H ions furnished by acid combine with one mole of ${ }^{-} OH$ 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.
