Ahstrae-Kinetics of the hydrogen evolution reaction (her) were measured at a rhodium electrode in a 1 M solution of KOH at various temperatures between 5 and 75Β°C. The rn-ts were conducted at a Rh wire electrode activated before every measurement by cycling in the range of potentials between -1.0 an

β¦ Synopsis
A potassium difluoride melt at 25O"C, in which minor amounts of water were dissolved, was electrolysed in order to investigate the kinetics of the hydrogen evolution at bright Pt electrodes.
The following electrode reactions are discussed:
