2.1.2 - Ficks Law Of Diffusion

Question 1

What Is Ficks Law Of Diffusion Used To Determine?

Answer 1

The rate of diffusion.

Question 2

What Does Ficks Law Of Diffusion State?

Answer 2

The larger the SA, difference in concentration and shorter the diffusion distance the quicker the rate.

Question 3

What Is The Formula For Ficks Law Of Diffusion?
(2 Points)

Answer 3

~ Rate Of Diffusion ∝ (Surface Area x Concentration Difference) / Thickness Of Membrane
Or
~ Rate = P x A x ((C1-C2) / T)

Question 4

In The Second Formula What Do All The Letter Mean?
(4 Points)

Answer 4

~ P = Permeability.

~ A = SA.

~ C1 - C2 = Difference in concentration.

~ T = Thickness.

Question 5

What Does Proportionality (∝) Mean?

Answer 5

Rate of diffusion will be doubled if the SA or concentration difference doubles or if the diffusion pathway doubles.
