qualitative thinking: For diffusion, we need to keep straight the difference between diffusion rate and iffusive flux. How do diffusive flux and diffusion rate differ? How do their units differ? Give an equation that relates the two. Based on Fick's equation for diffusive flux, what are some conditions that would increase flux and rate?

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
