Abstract

The reaction Gibbs energy is shown to be an intensive quantity with unitsof joules per mol. Many textbooks report it with units of joules. This results in confusion when cell potentials are used to calculate reaction Gibbs energy. The symbol n which appears in the Nernst equation is dimensionless.

- Unified Electroanalytical Chemistry: Application of the Concept of Electrochemical Equilibrium
  Robert Q. Thompson and Norman C. Craig
  Journal of Chemical Education2001 78 (7), 928
  Electroanalytical chemistry, encompassing both static and dynamic techniques, can be unified and best explained by invoking the concept of electrochemical equilibrium. Parallel to chemical equilibrium that occurs when -TΔStot = ΔG = 0, electrochemical ...
