✦ Synopsis

Electrareduction of ethylene derivatives was conducted on a smooth platinum electrode. Kinetic parameters and the study of the adsorption state of the test electrode lead to the conclusion that (i) the hydrogen atom and the organic reactant adsorb on different facets for different kinds of sites) and (ii) the first addition of the hydrogen atom to the reactant at a boundary bet&en the two facets (or the sit&) is ratedetermining. Difference in the rates among the ethylene derivatives is discussed in terms of the molecular properties calculated by CNDO/Z and EH methods.
