Kinetic Study and Mechanism of Mono Phenyl Hydrazo Phosphate (Ba-Salt) via Its Conjugate Acid Species

Abstract

Hydrolysis of mono phenyl hydrazo phosphate (Ba-salt) was
carried out in the acid region (0·1-7·0 mol dm³ ) at 98°C in aqueous
media. The acid-log rate profile has a rate maxima at
4·0 mol dm³ . Here mainly contribution of mono phenyl hydrazo
phosphate (Ba-salt) is involved in hydrolysis. The participation of
conjugate acid species and determination of theoretical rates has
been exhibited by ionic strength data. The observed rates were also
found in close agreement with the estimated theoretical rates derived
from the 2nd empirical term of Debye-Huckel equation. By
molecularity data the bimolecular nature of reaction is detected and
P-N bond fission has been strengthened by isokinetic relationship.
