Question

How can an electrochemical cell be converted into an electrolytic cell ?

• A. Applying an external opposite potential greater than $E^\circ_{\text{cell}}$.
• B. Reversing the flow of ions in salt bridge.
• C. Applying an external opposite potential lower than $E^\circ_{\text{cell}}$.
• D. Exchanging the electrodes at anode and cathode.

Answer 1

Answer: (A)

Applying an external opposite potential greater than $E^\circ_{\text{cell}}$.

Answer 2

To convert an electrochemical cell into an electrolytic cell, an external potential needs to be applied in the opposite direction. This applied potential should be greater than the standard cell potential $E^\circ_{\text{cell}}$. When this condition is met, the cell reaction reverses, and the electrochemical cell functions as an electrolytic cell.
