✦ Synopsis
The earlier reported observations of two reaction regions (I1 and 1;) overlapping within a range of potentials and indicating two different states, A and B, on an etched iron surface have been confirmed with Armco iron in KC1 solutions, and an analysis of the kinetic data of the two reactions has been carried out.
Both reactions can be accounted for by the same reaction scheme, the differences being due to different rds and adsorption patterns of an intermediate for the two reactions. The scheme is compatible with an earlier proposed model for the anodic dissolution reactions of iron and also with the type of effects which can be expected to arise from etching.
