Consider the electrode reaction O R Under the conditions that bulk concentrations

Consider the electrode reaction O + e = R. Under the conditions that bulk concentrations [O]*=[R]*=1mM, ko = 10-6cm/s, and a=0.3. 1. Calculate the exchange current density, jo=io/A in microamps/cm2 . 2. Draw a current density – overpotential curve for this reaction for currents up to 600 microamps/cm2 anodic and cathodic. Neglect mass transfer effects. 3. Draw log j vs. ? a curves for the current ranges in question 2.
