An electrochemical cell an behave like an electrolytic cell when

A

`E_(cell)=0`

B

`E_(cell) gt E_(ext)`

C

`E_(ext)gtE_(cell)`

D

`E_(cell)=E_(ext)`

Text Solution

Verified by Experts

The correct Answer is:
C
When external EMF applied `(E_(ext))` is greater than `E_(cell)`, electrons flow from cathode to anode, i.e., like an electrolytic cell.
