Consider a system similar to that in problem 1, but now with dissolved EO in liquid water. The temperature is 35 oC, the porous material has a void fraction () of 0.3 and a mean pore diameter of 1.2 nm. Just like with problem 1, you want to know the diffusion coefficient of EO inside the porous material. Calculate the binary diffusion coefficient, DAB, using the Wilke-Chang correlation and then use that value to calculate the effective diffusion coefficient, DAe, by considering the impact of the pore diameter and void fraction. Use the liquid density of EO of 0.882 g cm-3 to calculate its molecular volume and use that to also estimate the solute molecular diameter, ds.
