The hyclroysis reaction of N-benzoyl-2-phenylirIUdazole have been investigated spectrophometrically in water contairung O.5M with KCI at 25°C. H₃O+ cataIyzed reaction below pH 6 is related with mono protonated species and diprotonated species, suggesting that the mono protonated species is quiet stabilized by the phenyl substituent of the leaving group, whereas OH- catalyzed reaction might be proceeded through tetraheclral intermediate and the rate determining step seems to be change with pH. Appearent pKa value was 5.4.
