Question
The voltammogram below is recorded at a Au RDE (area 0.2 cm?, rotation rate 3600 rpm) for a solution containing 100 mM Ce* + 50 mM Ce³3+ in 3 M CH3SO3H in H2O. I/mA 0.04 (5) 0.02 (4) 0.00 -500 500 1000 1500 E vs SCE/mV (3) -0.02 (2) -0.04 (1) (a) Identify all the electrode reaction taking place (1–5) and indicate the rate-determining steps. (Use the 'electrochemical series'.)
