WebOct 21, 2015 · As the ratio gets smaller, it takes longer for items to diffuse. Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. WebHow does molecular weight affect diffusion? Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. What happens to diffusion rate as molecular weight increases? Both molecular weight and …

WebFeb 16, 2024 · Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.
