Expert Answer
See Eocell = Eocathode - Eoanode
This is the emf of the cell when no current is drawn through the cell. The conditions are standard conditions i.e. the temperature is 298 K and the concentration of the solutions is unity..
But when the concentration of the solutions change the cell potential decreases.
Therefore, nernst equation is followed under such conditions:
