(a) Choose all of the statements from below which correctly describe issues pertaining to the relationship between the emf of a reaction and its Gibbs free energy change. The Gibbs free energy change and emf values of a reaction have opposite algebraic signs (+ VS.-). Electron stoichiometry need not be used to interconvert a Gibbs free energy change and a reaction emf. A spontaneous reaction has a negative Gibbs free energy change and a positive emf. A coulomb of particles...
