We present calculations of the rate of electron transfer from a semi-infinite-jellium metal to a proton imbedded in a polanzable insulating medium. The model is interpreted to give values of (the slope of the voltage-log current characteristic of a metal-electrolyte interface. We use a form of the local density approximation to the Kohn-Sham local density variational technique, so that the model contains the quantum properties of the interacting electron gas.
