Question

When An Electrochemical Cell Behave As Electrolytic Cell?

Answer 1

Answer:

When, Ecell > Eext

Explanation:

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 1.1 V.

At this stage no current flow through the cell and if there is any further increase in the external potential then reaction starts functioning in opposite direction.

Hence, this works as an electrolytic cell.

Answer 2

Answer:

If an external opposite potential is applied on the galvanic cell, the reaction continues to take place till the opposing voltage reaches the value 1.1 V At this stage no current flow through the cell and if there is any further increase in the external potential then reaction starts fuctioning in opposite direction Hence, this works as an electrolytic cell.

Explanation:

When external EMF applied (Eext) is greater than Ecell, electrons flow from cathode to anode, i.e., like an electrolytic cell.
