An electrochemical cell an behave like an electrolytic cell when

A

`E_("cell")=0`

B

`E_("cell")gtE_("ext")`

C

`E_("ext")gtE_("cell")`

D

`E_("cell")=E_("ext")`

Text Solution

Verified by Experts

If an external opposite potential is applied on the galvanic cell and increased reaction continues to take place till the opposing voltage reaches the value 11V.
At this sstage no current flow through the cell and if there is any further increase in the external potential then reaction starts functioning in oppsoite direction.
Hence, this works as an electrolytic cell.
