Vv. Elkin et al., POLARIZATION HODOGRAPH OF THE 2ND-ORDER IMPEDANCE FOR THE CHARGE-TRANSFER PROCEEDING UNDER KINETIC CONTROL, Russian journal of electrochemistry, 34(2), 1998, pp. 126-132
A technique is proposed allowing one to interpret dependences of the i
mpedance constituents an the electrode potential and analyze trajector
ies traced our in the course of altering potential by the end of the i
mpedance vector (polarization impedance hodographs) for the electroche
mical reaction of charge transfer, The first-and second-order impedanc
es are considered from a unified viewpoint. Qualitatively, the polariz
ation hodograph for charge transfer proceeding under kinetic control i
s represented by two semicircles that smoothly transform into each oth
er. The semicircles correspond to either anodic or cathodic potentials
and lie within the second and fourth quadrants of the complex plane,
respectively.
