Fick Diffusion Coefficients for the System Acetone-Benzene-Methanol

Example 3.2.1 Fick Diffusion Coefficients for the System Acetone-Benzene-Methanol 

The Fick diffusion coefficients for the system acetone(l)-benzene(2)-methanol(3) in the volume average reference velocity frame are given in Table 3.2. Calculate the elements of [D] in the molar average reference velocity frame. 

D/47L4 The partial molar volumes for acetone, benzene, and methanol are 

SOLUTION The matrix [ ] is related to [D ] by the inverse of Eq. 3.2.12. Thus, the first step is the calculation of the transformation matrix and its inverse [B ] from Eqs. 

The inverse of this matrix can be calculated directly or from Eqs. 1.2.21 as follows
