The tungustophosphoric acid catalysed oxidation of cyclic alcohol (Cyclopentanol) by Nbromophthalimide (NBP) in 50% aqueous acetic acid medium in absence of mercuric (II) acetate and in presence of mineral acid was reported spectrophotometrically. The available spectral data was used for the verification of Beer-Lambert Law. The study reveals first-order kinetics for oxidant whereas fractional-order for substrate and catalyst PTA. The presence of mineral acid had insignificant effect whereas phthalimide shows retarding trends while increase in solvent polarity shows increase in rate of oxidation. A reasonable complex mechanism with mole ratio 1:1 was proposed consistent with the kinetic findings supported by thermodynamic parameters.
