Abstract
The kinetics of RuIII catalyzed reduction of hexacyanoferrate(III) [Fe(CN)6]3−, by atenolol in alkaline medium at constant ionic strength (0.80 mol dm−3) has been studied spectrophotometrically, using a rapid kinetic accessory. The reaction between atenolol and [Fe(CN)6]3− in alkaline medium exhibits 1:2 stoichiometry [atenolol:Fe(CN)63−]. The reaction showed first order kinetics in [Fe(CN)6]3− concentration and apparent less than unit order dependence, each in atenolol and alkali concentrations. Effect of added products, ionic strength and dielectric constant of the reaction medium have been investigated. A retarding effect was observed by one of the products i.e., hexacyanoferrate(II). The main products were identified by i.r., n.m.r., fluorimetric and mass spectral studies. A mechanism involving the formation of a complex between the atenolol and the hydroxylated species of ruthenium(III) has been proposed. The active species of oxidant and catalyst were [Fe(CN)6]3−and [Ru (H2O)5OH]2+, respectively. The reaction constants involved in the mechanism were evaluated. The activation parameters were computed with respect to the slow step of the mechanism, and discussed.
