We’re given the following electrochemical cell:
Since a battery is given, this is an electrolytic cell, where a nonspontaneous process is occurring. Since the process is nonspontaneous, an outside energy source (battery) provides energy for it to occur.
a. Label the anode and the cathode. Indicate the direction of electron flow. Label the terminals on the battery as positive or negative.
b. Indicate the half-reaction occurring at Anode. Express your answer as a chemical equation. Identify all of the phases in your answer.
c. Indicate the half-reaction occurring at Cathode. Express your answer as a chemical equation. Identify all of the phases in your answer.
d. Calculate the minimum voltage necessary to drive the reaction. Express your answer using two significant figures.
