In the present work the tris (Ferene) iror (II) complex has been applied for kinetic determinations of N-acetylcystcine ,phenol, 1,4-phenylendiamine , 2,4-diaminotoluene and 8-aminochinolin . Kinetic determinations of NAC , phenol and these amines were undertaken using fixed time method whereby absorbance of the his (Ferene) iron(II) complex was measured after 5 minutes of addition of Fe(III). The stability of the tris (Ferene) iron(II) complex in mixed aqueous organic cosolvent was studied and the kinetics determined. The order with respect to the complex is found to be unity and zero order with respect to acid. A suitable mechanism was postulated for the aquation of the above complex. The activation parameters were also determined.
