WebPS 4-S -1 MAT E 341 Applied Electrochemistry Problem Set 4 January 27, 2016 Due: February 3, 2016 1. The detection of ionic impurities in water is critical for some industrial processes for which stringent regulations and technical requirements are in place. WebIn electrochemistry, it is more common to use (activation) overpotential rather than Overpotential is This is the “extra voltage” which drives a Faradaic current. In terms of overpotential, the reaction rate is . Using , I=neAR where A is electrode area. Thus, I k= kI (1 ) / / 0 ⎡e −α neη BT − ⎣ e −αneη BT ⎤ ⎦
