For hydrogen at pt (a) Assign the voltametric features between +0.5 and 1.0 V and between-1.5 and -2.0 V to appropriate electrode reactions. Comment on the heterogeneous and homogeneous kinetics pertaining to these electrode reactions. (b) Why does the falloff in current appear between 0.7 and 1.0 V vs. QRE? (c) What constitutes the anodic and cathodic currents seen at -1.0 V vs. QRE?
