0:00 Order of magnitude
0:33 Two equations: Large vs small
0:46 Stoke-Einstein (Large)
1:20 When use which equation
1:46 Wilke-Chang (small)
2:52 Viscosity of solution! (T and C)
3:58 Short summary of mass transfer
Introduces the Stoke-Einstein equation for estimating mass diffusivity of large molecules in liquids and the Wilke-Chang equation for small molecules. At the end we also summarise a few things we have concluded about mass transfer (due to diffusion) so far.
