The Effect of Concentration on Cell Potential: The Nernst Equation. Recall that the actual free-energy change for a reaction under nonstandard conditions, ΔG, is given as follows: ΔG = ΔG° + RTlnQ. We also know that ΔG = − nFEcell (under non-standard confitions) and ΔGo = − nFEo cell (under standard conditions).

This is one of many videos provided by Clutch Prep to prepare.
