How Does Molecular Weight Affect the Rate of Diffusion?


The molecular weight affects the rate of diffusion because it's molecular mass, not weight. The larger mass atoms have a bigger physical appearance, and the rate of diffusion is decreased.

The greater the molecular weight the greater the
diffusion rate and molecular weight are inversely relating-the larger the weight, the slower the diffusion rate; and the smaller the weight, the faster the diffusion rate.
Diffusion and osmosis are central concepts in biology, both at the cellular and organ levels. They are presented several times throughout most introductory biology textbooks (e.g.
Yes NH3 will diffuse faster than HCl - diffusion is faster for smaller molecules.
