Answer the following questions about ECE-type reactions. A + e = B E" =-0.5 V (vs. SCE) BC C + e-DE-10 V (w. SCE)
(a) Sketch two cyclic voltammograms for two different scan rates in the range of 0.0 - -1.5 V, and predict how the size of four currents (reduction and oxidation of A and B, reduction and oxidation of C and D) change according to scan rate. Assume that compounds A, C, and Dare chemically stable and all electrochemical reactions are neistian.
(b) An RDE experiment was performed in the range of 0.0 - -1.5 V with the rotation speed being varied, from which n value was obtained. Predict how the apparent » value (reparera) changes according to rotation speed.
(c) An RRDE experiment was performed with the disk potential being varied in the range of 0.0 --- 1.5 V and the ring potential being fixed at 0.0 V. Predict how N-(-iplin) changes according to rotation speed.
