330045 How can an electrochemical cell be converted into an electrolytic cell?

1 Exchanging the electrodes at anode and cathode.
2 Applying an external opposite potential greater than \({\mathrm{\mathrm{E}_{\text {cell }}^{\circ}}}\).
3 Applying an external opposite potential lower than \({\mathrm{\mathrm{E}_{\text {celll }}^{\circ}}}\)
4 Reversing the flow of ions in salt bridge.

330046 Assertion :
For the Daniell cell,
\(\mathrm{Zn}\left \vert \mathrm{Zn}^{2+}\right \vert \left \vert \mathrm{Cu}^{2+}\right \vert \mathrm{Cu}\) with \(\mathrm{E}_{\text {cell }}^{\mathrm{o}}=1.1 \mathrm{~V}\), the application of opposite potential greater than \({\text{1}}{\text{.1 V}}\) results into flow of electrons from cathode to anode.
Reason :
\(\mathrm{Zn}\) is deposited at anode and \(\mathrm{Cu}\) is dissolved at cathode.
