The absolute enthalpy of neutralisation of the reaction:
will be
A
B
greater than 
C
less than 
D
57.33 
Text Solution
Verified by ExpertsThe correct answer is:
C
is the oxide of weak base and we know that heat of neutralisation of 1 eq. of strong acid with strong base is 
kJ/mol.
with weak base some heat is absorbed in dissociation of weak base.
Heat of neutralisation of weak base with strong acid will be less than 
kJ/mol.
