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:
B = ( 0.620 ) n F A D 2 3 v − 1 6 C {\displaystyle B=(0.620)nFAD^{\frac {2}{3}}v^{\frac {-1}{6}}C}
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 (cm2) D is the diffusion coefficient (see Fick's law of diffusion) (cm2/s) v is the kinematic viscosity (cm2/s) C is the analyte concentration (mol/cm3)
