We discuss the dependence of the diffusion coefficient andAbstractof the viscosity on the temperature and on the composition for ideal binary liquid mixtures, in particular for the system chlorobenzene + bromobenzene. The activation energy for dif-fusion is independent of the composition and exceeds the activation energy for viscous flow which is a linear function of the mole fractions.

The binary mixtures of cabontetrachloride with isobutylmethylketone and benzaldehyde were studied at 308.15 by measuring viscosities and densities. The derived and excess viscosities, activation energy of flow and Grunberg-Nissan parameters have been calculated. It was found that these parameters are satisfactorily used to predict the strength and nature of molecular interactions. It was found that the strength of interactions in the systems studied is in the following order: CCl4 + IBMK>CCl4 + BDKeywords: Binary liquid; benzaldehyde; carbontetrachlorideDOI: 10.3126/bibechana.v6i0.3932BIBECHANA Vol. 6, March 2010 pp.9-14
