Shown Below Is an Electrochemical Cell with Anode a and Cathode

question 191

Multiple Choice

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)
