THE HANGING MENISCUS ROTATING-DISK (HMRD) .3. APPLICATION TO A CHARGE-TRANSFER PRECEDED BY A CHEMICAL-REACTION IN EQUILIBRIUM

The hanging meniscus rotating disk (HMRD) is a configuration in which a cylinder of the electrode material is mounted without an insulating shroud. Despite the differences in the hydrodynamic boundaries introdu ced because of the meniscus of electrolyte that rises above the genera l surface level, the hydrodynamic behavior of the HMRD is similar to t hat of conventional rotating disks and it can also be used to study th e kinetics of simple charge transfer reactions. In this paper, the cur rent-rotation rate equations for a chemical reaction in equilibrium th at precedes the charge transfer reaction at the HMRD are developed. Th e applicability of the HMRD to the study of the kinetics of chemical r eactions in equilibrium in the bulk electrolyte is discussed.
