Consider water at 320 K and 4.7 atm (molar mass of 18 g/mol). This water has a tiny amount of carbon dioxide dissolved in it (molar mass of 44 g/mol). Realize that all calculations performed in this section are at the specified temperature and pressure. a. Employing Appendix I, determine the viscosity of this aqueous solution in units of cP (1 Pa's is equivalent with 1000 CP). Make sure you perform an interpolation. b. Now, evaluate the diffusion coefficient of carbon dioxide in this aqueous solution in units of cm/s. For this purpose, specifically employ the formula of Wilke and Chang. Of course, the viscosity you just determined is useful here, as well as other parameters found in Tables 24.4, 24.5, etc. c. Importantly, you can verify this value of the diffusion coefficient by employing one of the empirical values found in Appendix J. Please do so. d. I now claim that this value must also correspond with the diffusion coefficient of water itself (in this aqueous solution). Do you agree with me? Explain yourself.
