Question

(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.

A) The Gibbs free energy change and emf values of a reaction have opposite algebraic signs (+ vs. -).
B) Faraday's constant is not used to interconvert a Gibbs free energy change and a reaction emf.
C) A Gibbs free energy change involves moles of substances whereas an emf involves coulombs of electrons.
D) Faraday's constant is used to interconvert coulombs of electrons and moles of electrons.
E) The Gibbs free energy change and emf values of a reaction have the same algebraic signs (+ or -).
