Document Abstract
The catalytic effect of cationic micelles of cetyltrimethylammo- nium bromide (CTAB) on the MnO2-paracetamol (PCM) redox reaction has been examined spectrophotometrically in acidic medium at 298 K. The reaction demonstrates that the stoichio- metric ratio of MnO2 and PCM is 1:1. The reaction exhibited first order kinetics with respect to [MnO2] and [PCM] but a negative fractional order was observed with respect to [H2SO4]. Various effects such as ionic strength, dielectric constant, [Mn(II)], [salts] and temperature have been studied. The catalytic effect of CTAB has been treated quantitatively by the well known Menger Port- noy and Piszkiewicz model. The values of binding constant (K s), rate constant in the micellar phase (k m), cooperativity index (n) and dissociation constant (K D) have also been calculated. From the several observations, a reaction mechanism has been pro- posed and the rate law has been derived. Applying the Arrhe- nius equation, various thermodynamic
