The Levich equation is written as: = where I L is the Levich current (A), 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 2), D is the diffusion coefficient (see Fick's law of diffusion) (cm 2 /s), ω is the angular rotation rate of the electrode (rad/s), ν is the kinematic viscosity (cm 2 /s), C ...
An RDE cannot be used to observe the behavior of the electrode reaction products, since they are continually swept away from the electrode. However, the rotating ring-disk electrode is well suited to investigate this further reactivity. The peak current in a cyclic voltammogram for an RDE is a plateau like region, governed by the Levich ...
The Koutecký–Levich equation models the measured electric current at an electrode from an electrochemical reaction in relation to the kinetic activity and the mass transport of reactants. A visualization of the Koutecký–Levich equation. The graph shows the measured current as a function of the mass transport current for given kinetic current.
A Levich constant (B) is often used in order to simplify the Levich equation. [1] Furthermore, B is readily extracted from rotating disk electrode experimental data.. The B can be defined as: [2]
Displays an equation in a box. Template parameters [Edit template data] Parameter Description Type Status Indent indent One or two colons for an indent from the left, OR a valid CSS margin value. Leave blank for no indent.

Equation number: 2: The number of the equation, also used to generate the anchor. String: suggested: Anchor id: id: The anchor id. If you set this to "my-eqn" (no quotes), the link [[#my-eqn|see my equation]] will take you to the equation. Default Defaults to "equation-" + the equation number, if that is specified. String: optional
{{Convert}} uses unit-codes, which are similar to, but not necessarily exactly the same as, the usual written abbreviation for a given unit. These unit-codes are displayed in column 3 of the following tables. These are accepted as input by {{convert}} as the second and third unnamed parameters: {{convert|100|kg|lb}} → 100 kilograms (220 lb)
