At any given concentration difference,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. The rate of diffusion is inversely proportional to the size of the molecule. Smaller molecules have a higher rate of diffusion than larger ones. This is because they have a shorter distance to travel across the permeable surface and can move more easily through the pores or channels.
