b) In liquids the reasons of which molecular motions are effective to transfer b1) momentum ? b2) heat? b3) mass? Molecular motion Reasons Transferred quantity Momentum Heat Mass c) Express viscosity for liquids as a function of temperature. Discuss the effect of temperature and pressure on viscosity of the liquids. d) In an aqueous ionic solution how can you calculate the viscosity, diffusion coefficient and the limiting molar conductivity of an ion if the ionic mobility and ionic radius are known? Using the data given in Table 16B.2 for Rb+ calculate the viscosity, diffusion coefficient and limiting molar conductivity of Rbt at 25C. Ionic radius of Rb+ is 146 pm. Hint: Force per mole of ion, F= Ne where NA is the Avogadro's number and e is the electron charge. Page 2 of 3
