Please help me with the following True/False Q's?
1. Temperature can increase or decrease the rate of diffusion (I put T because increase in temp would mean faster so they would go through faster.
2. A molecule will travel across a permeable membrane against its conentration gradient.
3. Molecules that can cross a selectively permeable membrane will eventually establish a dynmaic equilibrium
4. The rate of diffusion is affected by solute concentration

2: If it's only a permeable membrane (and is not selective) then the concentrations on each side would be working to become equal on both. Think about that.
3: If something is *selectively* permeable, then would the object be equilibrium or something else?
4: Think back to the basic meaning of osmosis and diffusion. Things move from high -> low concentrations. So if something has a higher concentration, would it diffuse faster?
Didn't want to just answer your questions for you. Hope that leads you in the right direction.
