Q. For the feasibility of a redox reaction in a cell, its e.m.f. should be

NTA AbhyasNTA Abhyas 2022

Solution:

Any redox reaction would occur spontaneously if the free energy change $\left(\right.\Delta G\left.\right)$ is negative. $\Delta G^{o}=-nFE^{o}$
Where $n$ is the number of electrons involved, $F$ is the value of Faraday and $E^{o}$ is the cell emf. $\Delta G^{o}$ can be negative if $E^{o}$ is positive.
