A Levich constant (B) is often used in order to simplify the Levich equation. Furthermore, B is readily extracted from rotating disk electrode experimental data.
The B can be defined as:
where
* n is the number of moles of electrons transferred in the half reaction (number)
* F is the Faraday constant (C/mol)
* A is the electrode area (cm)
* D is the diffusion coefficient (see Fick's law of diffusion) (cm/s)
* v is the kinematic viscosity (cm/s)
* C is the analyte concentration (mol/cm)
