Abstract

The standard rate constants, k°, and transfer coefficients, α, for the reduction of Zn 2+ and Li + from dimethylsulphoxide, DMSO, + propylene carbonate, PC, solvent systems have been measured by cyclic voltammetry. The values of α are independent of solvent composition while the k° values, corrected for double layer effects, decrease monotonically with increasing DMSO concentration. It is found that log k° corr varies linearly with the Gibbs energy of transfer of the electroactive ion.
