It is shown theoretically and experimentally that the first catalytic pre-wave in the Ni\*+-NCS-system (the reduction of the [Ni(NC%] complex) at COOS-< (l\*O-1.5) X IO-\* M (cNC#-> twin+) and within a wide range of ionic strength I can be described by a simplified kinetic equation based on the assu
