Why is the peak-to-peak separation of cyclic voltammetry is 57 mV? I'm studying CV, and I wonder if I can calculate the peak-to-peak separation of CV for a reversible redox system.

I found that the separation is 57 mV on my textbook, and my teacher taught me that is can be calculated theoretically using Nernst equation,
but I think it is more complicated.

Is it easy enough (for sophomore) to calculate the value?
And if it is, I want to know the way.

(Sorry for my poor English)
The derivation of equation for cyclic voltammetry requires a lot of advanced calculus and differential equations based on the Fick's law of diffusion. This is not to discourage you but to show that the teacher is oversimplifying it. The derivation are provided in Allan J. Bard's Electroanalytical Chemistry. Why are they teaching cyclic voltammetry in sophomore classes?
