The electrochemical impedance for infinite and finite diffusion processes was described, and the locus of the impedance was discussed through comparison of the experimental results with the theoretical ones. The charge transfer resistance Rct and the polarization resistance Rp were compared with the current i and the slope of the polarization curve for the reduction of K3Fe(CN)6. The physical meanings of Rct and Rp in the diffusion impedance were discussed. It was confirmed that Rct-1 was related to the reaction rate. The theory to apply the diffusion impedance to the analysis of corrosion reaction was revealed.
