Transcribed Image Text:
2. A solution of the chemical compound X in its oxidized form was studied by cyclic voltammetry. The
resulting voltammogram is shown below.
+20
Current (μA)
0
-20+
+0.9
->
+0.7
+0.5
+0.3
+0.1
Working electrode voltage (vs. reference electrode)
The working electrode voltage was initially set to +0.9 V and was slowly decreased to +0.1 V to form
the top (cathodic) wave. Then the electrode voltage was swept back to +0.9 V to form the bottom
(anodic) wave. The peak of the cathodic wave occurred at +0.478 V, while the peak of the anodic
wave occurred at +0.534 V.
(A) Calculate the reduction potential of compound X relative to the reference electrode used.
[5 points]
(B) Calculate the number of electrons transferred in the reduction half-reaction of compound X.
[4 points]
(C) State whether the reduction of compound X is reversible, and how you know. [2 points]
