All other factors being equal,the rate of diffusion across a permeable surface will be greater for small molecules than for larger ones.

Question

Quizplus · Accepted Answer

This statement is true according to Fick's Law of Diffusion, which states that the rate of diffusion is proportional to the surface area and concentration gradient, and inversely proportional to the thickness of the membrane and the size of the molecule. Therefore, smaller molecules will diffuse more quickly through a permeable surface than larger ones, all other factors being equal.
