JEE Mains Model Paper 22

The enthalpy of neutralization of a weak monobasic acid in IM solution with a strong base is -56.1 KJ mol−1 whereas the enthalpy of ionization of the acid is 1.5 KJ mol−1 and ΔHequivalance+ of strongacid against a strong base is -57.3 KJ equi−1 The per cent ionization of the weak acid is
