http://www.math-principles.com/2014/09/electrochemistry-problems.html WebEIS data are commonly analyzed by fitting to an equivalent electrical circuit model. Most of the circuit elements in the model are common electrical elements such as resistors, capacitors, and inductors. To be useful, the elements in the model should have a basis in the physical electrochemistry of the system.
The Tafel equation is an equation in electrochemical kinetics relating the rate of an electrochemical reaction to the overpotential. The Tafel equation was first deduced experimentally and was later shown to have a theoretical justification. The equation is named after Swiss chemist Julius Tafel." It … See more An other equation is applicable at low values of polarization $${\displaystyle \eta \simeq 0V}$$. In such case, the dependence of current on polarization is usually linear (not logarithmic): See more • Overpotential • Butler–Volmer equation • Electrocatalyst See more • Media related to Tafel equation at Wikimedia Commons See more • Burstein, G.T.
