how one can find out from cyclic voltametry measurement whether the oxidation/reduction is one electron or two electron
Maybe, I guess you can get the area of the peak, through the area to get whether one or two electrons participated. Just guess, never tried.
1) Koutecky-Levich (K-L) plot in accordance with the speed of rotating disk electrode
- You should use this equation with that all the coefficients and constants are exactly the same with your experimental setup such as electrolyte type, electrolyte concentration. rotating speed and so on.
2) Checking the reference
- Compare your experimental data with other literatures
For reversible systems the equation (Ep1 - Ep2)= (59 mV)/2. But, you can obtain the number of electrons interchange using de Randles - Sevcik equation if you have the coeficiente of diffusion, the geometric area of electrode, the scan velocity, and the concentratión over the electrode.
You can use the Cotrell equation to calculate the number of electrons. In this case you must change the technic and to use amperometry.
