For example, in cyclic voltammetry the redox potential of cathodic or anodic peak or both shifted with increasing/decreasing the analyte concentrations. All other parameters remain constant.
The electrochemical potential will follow the Nernst equation, which is dependent on the activity of the redox species. Does the change in potential and concentration match the Nernst equation?
Do both reduction and oxidation peaks shift in the same direction, or do they get closer/further apart?
The redox system is irreversible where we have only the oxidation peak and anodic peak potential decreases with increasing concentration of the analyte.
As our colleges said, the peak potential is dependent of the concentration of the specie in the solution.
However, I've no clear that the peak potentials shift toward lower values when increasing its concentration in irreversible processes, as I've seen the opposite during zinc deposition.
On the other hand, can you define more your question?
