Nitrogen as residual gas with, say, p*(N2) = 4 $ 10–6 bar in an evacuated ampoule) is chosen as reference, comparison becomes possible. , p*(Cl2) when using tellurium(IV)-chloride) chosen for the calculation, relative values for the transport efficiencies of individual gas species are obtained only, never absolute values. As the transport efficiencies calculated are only for the purpose of deriving the dominating transport reaction, the relative values are sufficient. As already stated, direct comparison of transport efficiencies of different transport systems requires calculation of the w(i) always with the same balance pressure of an inert gas.
Since the entropy ΔrS 0 of a reaction under consideration can be estimated in a rather simple way from the number of gaseous molecules in its reaction equation, the values for ΔrH 0 and T that will allow a significant transport rate can be easily calculated. 8. 1 bar. 2 amounts on average to ΔrS 0 = −85 J $ mol−1 $ K−1. This value deviates significantly from the abovementioned estimate of ±140 J $ mol−1 $ K−1 since for atomic gaseous species the contributions from rotation and vibration to the partitition function become zero.
