A Mechanical Analogue for Chemical Potential
Samuel V. Glass and Roger L. DeKock
Calvin College, Department of Chemistry, 3201 Burton Street, S.E., Grand Rapids, MI 49546-4388
Cover
February 1998
Vol. 75 No. 2
p. 190
Abstract
We present an analogy which relates the one-dimensional mechanical equilibrium of a rigid block between two springs and the chemical equilibrium of two perfect gases. This mechanical analogue illustrates the concepts of the chemical potential, the extent of reaction, and the reaction Gibbs energy.
