Symposium: A Controversy about the Gibbs Function
The Gibbs Function, Spontaneity, and Walls
R. J. Tykodi

May 1996
Vol. 73 No. 5
p. 398

Abstract
For the expansion-into-the-vacuum process involving a saturated vapor, previously analyzed by Schomaker and waser and by myself, I assert that in general Delta G (composite) is undefined and that for the special case of bulbs with perfectly rigid walls Delta G (composite) is weakly positive. I show that the seemingly contradictory results of Schomaker and Waser are merely the consequences of their use of eccentric or anti-conventional terminology: they calculate the change in the Availability function for the process and call that change "Delta G (composite)".
