Diffusion von gelöstem Wasserstoff und Deuterium in flüssigem Ammoniak

Diffusion coefficients of H2 and D2 in liquid NH3 were determined from rates of solution at constant partial pressure of the gases (9 atm) in the range -60 to + 1 0 °C. D0(H2) = 9.4±0.4 ; D0(D2) = 7.4+0.4 cm2/sec; ΔE(H2) =2090 ± 30 ; ΔE(D2) =2030 ± 30 cal/mole. The mechanism of diffusion and the isotope effects are discussed on the basis of the structure of liquid NH3
