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
In unbuffered aqueous solution, the hydrogen evolution at iron electrodes is usually first order in hydrogen-ion dependence at pH below about 7 and pH independent at higher pHC1-41. This indicates that hydrogen ions and water molecules are the main electroactive reactants for this reaction in acid a
