ELECTROCHEMICAL KINETICS OF FERRI-FERROCYANIDE COUPLE ON PLATINUM

The current Impulse technique was used to study the electrochemical kinetics of the ferri-ferrocyanidecouple. The exchange rate of the reaction was strongly dependent on the oxidation state of the electrode surface. The transfer coefficient and the activation energy do not appear to be affected by surface oxidation. All experimental evidence points to a simple first order electron transfer reaction. The results of the investigation were in substantial concordance with those measured by other techniques when surface oxidation effects are taken into account. © 1969, American Chemical Society.
