Redox-Electroadsorption Reaction (E-EAR) at a Rotating Disk Electrode (RDE)
Redox-Electroadsorption Reaction (E-EAR) at a Rotating Disk Electrode (RDE)
This Demonstration shows plots of dimensionless current density versus potential ( versus ) curves, and changes of electroactive species concentrations, and the fractional surface coverage of adsorbed species , , for a redox-electroadsorption reaction (E-EAR) reaction under steady-state conditions at an RDE.
