Question

What are conditions for a galvanic cell to become a reversible cell?

Answer 1

Rechargeable batteries require the use of a reversible reaction. An electrochemical cell being forced in its non-spontaneous direction is referred to as an electrolytic cell. There are two situations that factor into the reversibility of reactions used in electrochemical cells.

Answer 2

$\huge\mathfrak\color{blue}{Answer}$

A reversible cell should satisfy the following conditions: i)When the external emf of the cell is infinitesimally greater than the emf of the cell, then current should flow through the cell and the cell reaction of the cell should get reversed.
