Question

Define electrochemical cell. What happens if external potential applied becomes greater than $E_{c e l l}$ of electrochemical cell?

Open in App

Solution

Electrochemical cell is a device used for production of electricity from energy released during spontaneous chemical reaction. If external potential applied becomes greater than $E_{c e l l}^{\circ}$ of electrochemical cell, then the reaction gets reversed.
