Micellar effects upon the forward and reverse processes corresponding to the reaction between acetonitrile pentacyanoferrate(II) and pentaamminepyrazineruthenium(II)

The kinetics of formation and dissociation of the binuclear complex [ Fe II ( CN ) 5 pzRu II ( NH 3 ) 5 ] - were studied in sodium dodecylsulfate (SDS) micelles. The results were interpreted by using the Pseudophase Model for the dissociation process. At the same time, a modified Pseudophase Model was used to explain the results obtained in the formation process. In this modified model, the influence that the surface potential of the micelles provokes on the formation process was taken into account.
