It relates the potential of an electrochemical cell to concentrations in the cell reaction. It also is useful because it can be used for nonstandard conditions too.

It ties the max potential of an electrochemical cell to respective cell concentrations that are in the battery and the conditions of it can be assumed regular as @25 degrees C or also for non-regular conditions.

The Nernst equation allows us to calculate the Ecell value at non-standard conditions given the reaction quotient. At the same time, the Nernst equation can also be used to calculate the reaction quotient or the equilibrium constant given Ecell and Ecell under standard conditions.

Return to “Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH)”
