The thermodynamic properties and mechanism of a quachloroiridium(III) Catalyzed oxidation of pharmaceutical drug(Paracetamol) by acidic solution of potassium bromated(KBrO3) at 350C. The reaction followed first order kinetics with respect to Ir (III) and potassium bromated (KBrO3). Rate of reaction exhibits zero order and fractional positive order kinetics with respect to [KCl] and [PA] respectively. The rate of reaction decreased with increasing [H+] was observed for the oxidation of paracetamol. Negligible effect of [Hg(OAC)2 ] and ionic strength of the mediumwas observed at different temp.(300 C to 450 C) were utilized to calculate the activation parameters. The reaction between potassium bromate and paracetamol in acid medium exhibits 1:2 stoichiometry. Quinoneoxime and acetic acid have been identified as main oxidation products of the reactions. Feasible mechanism has been proposed conforming to the kinetics, stochiometry and product of the reaction. The rate law has been derived from obtained kinetic data.
