Description: The Tafel equation relates the electrochemical reaction rate to overpotential.

TeX format: \Delta V = A ln\left(\frac{i}{i_0}\right)

ΔV {\DeltaV} = Overpotential (V) {V}
A {A} = Tafel slope (V) {V}
i {i} = Current density (Am-2) {Am^{-2}
i0 {i_0} = Exchange current density (Am-2) {Am^{-2}}
Keywords: Tafel • corrosion • electrochemical • potential • cathode • anode • electrode • reaction • overpotential
