Diffusion coefficent
The empirical equations for estimating the diffusion coefficient in infinite solution which are presented in Reid, 1987 all show a linear dependency on temperature. We thus simply scale the experimentally obtained diffusion coefficient of Ferrell and Himmelblau by the temperature.
