The conductance data have been analyzed by the 1978 Fuoss conductance-concentration equation in terms of the limiting molar conductance (Λ0), the association constant (KΛ) and the association diameter (R). The viscosity data have been analyzed by the Jones-Dole equation for the associated electrolytes to evaluate the viscosity B-coefficients of the electrolyte. These data have also been analyzed by the transition-state treatment to obtain the contribution of the solutes to the free energy of activation for viscous flow of the solution. The ionic contributions to the limiting molar conductance (Λ0), the viscosity B-coefficient and the free energy of activation for viscous flow have been estimated using the "reference electrolyte” tetrabutylammonium tetraphenylborate (Bu4NBPh4). Slight ionic association was always found for this salt in this solvent medium. The tetrabutylammonium ion is found to be unsolvated whereas the thiocyanate ion undergoes solvation in acetonitrile in the temperature range investigated here. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Chakraborty Jayanti Moitra aut Das Bijan aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/2/2004(2004-02-01), 219-230 0942-9352 218:2/2004<219 2004 218 zpch https://doi.org/10.1524/zpch.218.2.219.25926 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.2.219.25926 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Chakraborty Jayanti Moitra aut NATIONALLICENCE 700 1- Das Bijan aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/2/2004(2004-02-01), 219-230 0942-9352 218:2/2004<219 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
