The change in free energy for a reaction, $\Delta$G, depends on the stoichiometric coefficients used in writing the reaction, but cell potentials, E, do not depend on these coefficients. Which statement accounts for this difference?

Question

Quizplus · Accepted Answer

The change in free energy, ΔG, depends on the reaction and the amount of material reacting, as it is defined as the energy available to do work per mole of reaction. Therefore, the stoichiometric coefficients used in writing the reaction will affect the value of ΔG. In contrast, the cell potential, E, only depends on the composition of the cell and the redox potential of the reactants and products, regardless of the stoichiometric coefficients used to write the reaction.
