The magnitude of enthalpy of neutralisation of a weak acid is smaller than that of a strong acid.

The enthalpy of neutralisation of a weak acid is …………….. than that of a strong acid. The difference of the latter form the former is known as enthalpy of……………of the weak acid.

The enthalpy of neutralisation of a weak acid in 1 M solution with a strong base is -56.1 kJ mol^(-1) / If the enthalpy of ionization of the acid is 1.5 kJ mol^(-1) and enthalpy of neutralization of the strong acid with a strong base is -57.3 kJ "equiv"^(-1) , what is the % ionization of the weak acid in molar solution (assume the acid to be monobasic)?

Assertion(A) : The value of enthalpy of neutralization of a weak acid by strong base is numerically less than 57.1 kJ . Reason(R ) : All OH^(-) ions of strong base are not completely neutralized by H^(+) ions obtained from acid.

The enthalpy of neutralization of a Weak monoprotic acid (HA) in 1 M solution with a strong base is -55.95 KJ/mol . If the unionized acid required 1.4 KJ/mol heat for it's comptate ionzatation and enthalpy of netralization of the strong monobasic acid with a strong monoacidic base is -57.3 KJ/mol . What is the % ionzation of the weak acid in molar solution ?

Assertion(A) : The value of enthalpy of neutralisation of strong acid and weak base is numerically less than 57.1 kJ . Reason(R ) : All the H^(+) ions furnished by 1g equivalent of a strong acid are not completely neutralized by the OH^(-) ions from the weak base.
