M. Zameela et al., KINETICS AND MECHANISM OF RUTHENIUM(III)-CATALYZED OXIDATION OF SELENIUM(IV) BY MANGANESE(III), Journal of the Indian Chemical Society, 75(2), 1998, pp. 63-66
The title reaction is first order each in oxidant and catalyst and ret
arded by Mn-II. The order in Se-IV is unity at lower concentrations an
d fractional at higher concentrations. Increase in [H+] retards the ra
te of the reaction but variation in ionic strength has negligible effe
ct, A suitable mechanism involving Ru-VII as active oxidising species
is proposed.
