Hydrogen fusion may require a mixture of liquefied or frozen D2 and T2. The equilibrium constant of the exchange reaction describes the composition of this fuel. We have calculated the equilibrium constant K/sub DT/ for the reaction D2 + T2 = 2DT in the 4.2 to 100 K temperature range. The results agree well with previous calculations at 25, 50, and 100 K. Calculations at temperatures below 25 K have not been published previously. In the 16.7 to 33.3 K temperature range, which includes the triple point, K/sub DT/ can be represented by K = 2.995 exp( -10.82/T). The values of the analogous equilibrium constants for H2-D2 and H2-T2 are also given in the 4.2 to 50 K temperature range.

Equilibrium constants were calculated for the gas-phase isotopic exchange reactions C2H2 + C2D2 = 2C2 HD and C2H2 + D2O = C2D2 + H2O at temperatures ranging from 40 to 2000°K. No corrections to the harmonic approximation were made. The results agree quite well with experimental measurements.

Hydrogen fusion will require a mixture of liquefied or frozen D2 and T2. The equilibrium constant of the mixture describes the composition of this fuel. We have calculated the equilibrium constant, K/sub DT/, for the reaction D2 + T2 = 2DT in the 4.2-100 K temperature range. The results agree well with previous calculations at 25, 50, and 100 K. No calculations at temperatures below 25 K have been previously published.

A simple calculational method for deducing equilibrium mixtures in isotopic exchang reactions, in particular those involving mixed hydrogen isotope lithium hydride-hydrogen systems, is described. The method relies heavily on an approximate graphical technique. Several examples based on the Li(D,T)-DT system are discussed using assumed values of equilibrium constants for this particular system.

In 1931 Vrey, Brickwedde, and Murphy discovered the hydrogen isotope deuterium. The isotopic enrichment was found to arise from the fact that the electrolysis oflight water is faster than of heavy water [1,2]. This success showed that although different isotopes of an element behave identically from a chemical standpoint the different isotopic masses nevertheless lead to both isotope effects on equilibrium as well as on rate constants of chemical reactions. Soon, ratios of equilibrium constants of isotopic reactions were called "equilibrium isotope effects" (EIE), ratios of isotopic rate constants "kinetic isotope effects" (KIE). Isotope effects have been found to be especially large for those elements which are directly involved in bond breaking and bond formation during the reaction studied [3]. Such effects are, therefore, referred to as "primary". Isotopic substitution in atomic sites which maintain all chemical bonds with their neighbors during the reaction of interest leads then only to smaller "secondary" isotope effects. Because of the unique mass relation between the different hydrogen isotopes hydrogen/deuterium isotope effects are particularly large and have attracted most attention. The largest contributions to these effects arise from changes in the vibrational frequencies of the reactants. The theory of equilibrium isotope effects has been founded by Vrey [4] and Bigeleisen [5,6] and has widely been accepted [3].
