Redox Reaction (EE) at a Rotating Disk Electrode (RDE)
Redox Reaction (EE) at a Rotating Disk Electrode (RDE)
This Demonstration plots the current density versus the potential for a redox EE reaction ( under steady-state conditions at a rotating disk electrode. Simulated concentration profiles are shown, along with linearized (piecewise linear) concentration profiles of electroactive species according to Levich theory. IUPAC conventions are used.
