Question
Shown below is an electrochemical cell with anode a and cathode c. Both the anode and the cathode are inert electrodes. The liquid shown in compartment b of the cell is molten potassium chloride, KCl(l).
Determine whether this is a galvanic or an electrolytic cell and give the reaction occurring at the anode and the reaction occurring at the cathode.
A) Electrolytic cell
Anode reaction: K(s) -> K+(l) + e-
Cathode reaction: Cl2(g) + 2e- -> 2 Cl-(l)
B) Electrolytic cell
Anode reaction: 2 Cl-(l) -> Cl2(g) + 2e-
Cathode reaction: K+(l) + e- -> K(s)
C) Galvanic cell
Anode reaction: K(s) -> K+(l) + e-
Cathode reaction: Cl2(g) + 2e- -> 2 Cl-(l)
D) Galvanic cell
Anode reaction: K(s) - K+(l) + e-
Cathode reaction: Cl2(g) + 2e- -> 2 Cl-(l)
