Vignettes in the history of chemistry. 1. What is the origin of the Gibbs–Helmholtz equation?

Abstract

This column is intended to address questions students and teachers may have about the historical origins of a symbol, name, concept or experimental procedure found in their textbook. If there is a specific subject you would like to see addressed in the series, feel free to e-mail your queries to Dr. Jensen at the above address. This particular installment traces the historical origins of the well-known Gibbs–Helmholtz equation and casts doubt on the role of Gibbs in its formulation. Target audience: chemistry courses at all levels depending on the subject being discussed.
