Question

What happens if external potential applied becomes greater than e°cell of electrochemical cell?

Answer 1

the cell reaction move towards backward direction

Answer 2

Welcome dear,

● Electrochemical cell -
- An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions.

● Answer -
- If the external potential applied become greater than E° cell of electrochemical cell, the reaction gets reversed.
- Current flow gets reversed and cell starts to get recharged.
- That is it acts as electrolytic cell.

Hope this helps you...
