One method of studying diffusion in liquids used by Thomas Graham is that shown in Fig. 2.1-2(b). It consists of a small bottle of solution immersed in a large bath of solvent. Calculate the solute concentration in the bath as a function of time, and showhow this variation can be used to determine the diffusion coefficient. no 2.Dry ice is placed in the bottom of a capillary tube 6.2 cm long. Air is blown across the top of the tube. Calculate the ratio of the total flux to the diffusion flux halfway up thecapillary for the following conditions:
(a) A temperature of - 124 C, where the vapor pressure is 5 mm Hg. Answer: 1.00.
(b) A temperature of - 86 C, where the vapor pressure is 400 mm Hg. Answer: 1.45.
