Influence of the acidity of the iodous acid solution system on the kinetics of the disproportionation reaction

Influence of the acidity iodous acid (HOIO) solution system on kinetics disproportionation reaction is examined in aqueous sulfuric (0.125 moldm-3 ). The rate constants were determined at 285, 291, 298 and 303 K based data obtained under stationary conditions. calculated increase with increasing temperature for different values iodate concentrations. average activation energy 46 kJmol-1 was chosen interval, by a graphical method. pseudo-equilibrium concentrations kinetically important catalytic species H+ , H2OI+ i IO3 - given experimental conditions equilibrium dissociation reactions acids quasi-stationary state. estimated are predominant higher than concentration protonated ion .
