But what if the cell concentrations are not at standard states of 1.0 M concentrations? We can determine the cell potential under nonstandard conditions by adding a term that corrects for - deviations from standard states. The equation that Using the Nernst equation, cell potentials can be calculated from standard cell potentials and known concentrations. According to the Nernst equation, any change to the cell that increases Q decreases E cell, while any change that decreases Q will increase E cell.Thus, adding reactant or removing product increases E cell.Removing reactant or adding product, which is what the reaction is doing 2005-12-20 Nernst equation is a general equation that relates the Gibbs free energy and cell potential in electrochemistry. It is very helpful in determining cell potential, equilibrium constant etc.
