Inverse and rapid electrode reaction rapidly reduces (or increases) the reaction ionization concentration in the liquid layer on the electrode surface->; The concentration gradient of the reaction between the electrode surface and the solution changes from->; Concentration difference polarization->; The separation concentration of the liquid layer on the electrode surface determines the deviation between the electrode potential and the electrode equilibrium potential, which is called concentration potential.
electro chemical polarization
Electrode reaction speed is slow->; The current density causes the accumulation of electrode charges->; Electrochemical polarization->; The electrode potential depends on the deviation between the accumulated charge potential of the electrode and the equilibrium potential of the electrode.
Polarization is the same as electrochemical polarization 2, which is dominant.
