Question

which of the following factors would decrease the rate of diffusion? (select all that apply) check all that apply increased molecular weight decreased molecular size larger concentration gradient denser media smaller concentration gradient

Explanation:

Diffusion rate is inversely related to molecular weight and directly related to concentration gradient. Heavier molecules and a smaller concentration gradient slow down diffusion. Denser media also impede the movement of diffusing particles. Smaller molecular size and larger concentration gradient increase the diffusion rate.

Answer:

• increased molecular weight
• denser media
• smaller concentration gradient
