%X Bertrand and Burchfield proposed that the equilibrium constants K and the (standard) enthalpies &#916;H of isotopic exchange reactions are related by the equation  K = Kstatexp(-&#916;H/RT) in which Kstat is the statistical (random) equilibrium constant. The application of this equation to deuterium exchange reactions for which experimental K and &#916;H values are available suggests that it is a good approximation at 298 K. In this paper we present a statistical mechanical analysis to account for the success of the equation and to point out its limitations.
