Popis:	The kinetics and mechanism of the reaction of H2O2 with K[RuIII-(PDTA-H)Cl]·2H2O 1 (L = propylenediaminetetraacetic acid) and K[RuIII(HEDTA-H)Cl] 2 (L = hydroxyethylethylenediaminetriacetic acid) was studied by stopped flow spectrophotometry at pH = 3.4 and μ = 0.1 M (KCl) at various concentrations of H2O2 and at different temperatures. The μ-peroxo complex [RuIVL]2O2 (L = PDTA 3, HEDTA 4) was found to be the final product in both cases. The formation of μ-peroxo complexes 3 and 4 was first order in H2O2 and RuIIIL complex concentrations. The values of thermodynamic as well as activation parameters for the interaction of H2O2 with RuIIIL complexes are reported.
