Received Date: 17 April 1997

The diffusion coefficients(D_app) and the heterogeneous electron-transfer rate constants(k_s) for ferrocene and its seven derivatives in MPEG/LiClO₄ electrolyte were determined by using steady-state voltammetry.The two parameters increase with increasing temperature,indicating Arrhenius behavior.The effects of the nature of electroactive solute molecules on D_app,k_s,and the half-wave potentials(E_1/2) are discussed.
