Kinetics Of

The kinetics of the electron transfer reaction between tetraammine(pyrazinecarboxylate)cobalt(III), [Co(pyrazinecarboxylate)(NH3)4]2+, and hexacyanoferrate(II), [Fe(CN)6]4- was studied in aqueous solutions in the presence of DNA at concentrations 0-2.28 · 10-3 mol dm-3. A decrease in the rate constant with increasing DNA concentration was observed. The results are interpreted on the basis of the pseudophase model. The meaning of its parameters for the second-order reaction is discussed.
