D)the Nernst equation.
E)the Faraday equation.

Question

Quizplus · Accepted Answer

The Nernst equation is a mathematical equation that relates the standard potential to the standard free-energy change for redox reactions. It takes into account the concentrations of the reactants and products and allows for the calculation of the non-standard potential under non-standard conditions. Therefore, the Nernst equation is the best choice for this question.
