1) Suppose that cyclic voltammetry is carried out for one-electron reduction of a species, O, with a diffusion coefficient of 10–5 cm2 /s using a 20 µm-radius spherical electrode. Sketch a cyclic voltammogram with its unique features at the scan rate of 10 V/s. Identify an appropriate equation from the textbook (Electrochemical methods) and use the equation to explain quantitatively why you think these features are observed. Assume that the reaction is reversible.

6) Voltammetry - In linear scan voltammetry, the diffusion current is proportional to the concentration of the species being reduced. In one experiment 250.00 mL of a 6.00 x 104 M Cd2+ (aq) solution was analyzed using a mercury electrode. The voltammetry scan from -0.6 to -1.2 V took 3.40 minutes to complete.
