30. 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 its complete ionization and enthalpy of neutralization of the strong monobasic acid with a strong monoacidic base is –57.3 kJ/mol, what is the % ionization of the weak acid in molar solution
(a) 1%
(b) 3.57%
(c) 35.7%
(d) 10%
