Abstract
The electrochemical oxidation of ethylene on platinum electrodes in 1N sulfuric acid at 80 °C was studied by the potential sweep method over a wide range of sweep rates . The results were compared with those obtained previously under steady‐state conditions. Over three decades of sweep rate an apparent Tafel slope of approximately was observed. This was shown to be consistent with the behavior for a totally irreversible diffusion‐controlled reaction. In the same region the peak potential was found to shift 65 mv/decade increase in sweep rate and the peak current was proportional to the square root of the sweep rate with a proportionality constant in agreement with the calculated value.
