First, we must understand what diffusion is! Diffusion is the movement of particles from a high concentration to a lower concentration, in order to reach equilibrium. Cells in particular need this to maintain homeostasis, or an internal equilibrium (stability).

Do you mean molecular size or composition, perhaps? Bigger particles are harder to move than smaller molecules. Additionally, physical constitution of a particle will affect the rate of diffusion. Think of a mouse squeezing under a door as compared to a rock, of the same size. A mouse will more easily be able to squeeze through the gap

Edit

The rate of diffusion is inversely proportional to square root of its inverse of its molecular weight

i think you mean molecular mass. and bigger molecules diffuse slower than smaller molecules because fewer molecules can fit through the membrane.

What factors affect the diffusion rate?

Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.


What three things can affect the rate of diffusion?

Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.


How does pressure affect the rate of diffussion?

Higher pressures cause more molecular collisions which in turn causes a greater rate of diffusion. The opposite is also true - lower pressures cause a decreased rate of diffusion.

How does molecular size affect diffusion rate?

Rate of diffusion is indirectly proportional to the molecular mass. This means that for a heavier particle, (i.e, higher molecular mass), the rate of diffusion is slower because they would have to travel the same distance with more energy compared to smaller molecules. Imagine a fat man trying to run and a slimmer man, the fat man would require more energy.Read more: What_is_the_relationship_between_the_rate_of_diffusion_and_the_molecular_mass_of_a_substance
