The enthalpy of neutralization of a weak acid in \[1\text{ }M\] solution with a strong base is\[-\,56.1\,kJ\ mo{{l}^{-1}}\]. If enthalpy of ionization of the acid is \[1.5\text{ }kJ\text{ }mo{{l}^{-1}}\] and enthalpy of neutralization of the strong acid with a strong base is \[-\,57.3\text{ }kJ\text{ }equi{{v}^{-1}},\] what is the % ionization of the weak acid in molar solution (assume the acid to be monobasic)?
