Question

rate of diffusion
identify how each of the factors influence the rate of diffusion.
increase
decrease
high density solvent
large molecules
low temperature
low density solvent
large difference in concentration across the membrane
increase in temperature

Explanation:

• High density solvent: Slows down diffusion as molecules have more resistance moving through it.
• Low temperature: Reduces kinetic energy of molecules, decreasing diffusion rate.
• Large molecules: Move more slowly, decreasing diffusion rate.
• Low density solvent: Allows molecules to move more freely, increasing diffusion rate.
• Increase in temperature: Increases kinetic energy, increasing diffusion rate.
• Large difference in concentration across the membrane: Drives more rapid diffusion from high - to low - concentration areas.

Answer:

Increase: Low density solvent, Increase in Temperature, Large difference in concentration across the membrane
Decrease: High density solvent, Low temperature, Large molecules
