Factors Affecting the Rate of Diffusion

Vocabulary flashcards detailing how concentration gradient, surface area, temperature, solubility, membrane thickness, and molecular size affect the rate of diffusion.

Concentration gradient of the substance

A factor influencing diffusion where the greater the gradient is, the higher the diffusion rate.

Membrane surface area

A factor influencing diffusion where the greater the surface area is, the higher the diffusion rate.

Temperature of the medium

A factor that is in direct proportion with the diffusion rate.

Solubility of the molecules

A factor influencing diffusion where the greater the solubility is, the higher the diffusion rate.

Thickness of the membrane

A factor influencing diffusion where the less the thickness of the membrane is, the higher the diffusion rate.

Molecular size of the substance

A factor influencing diffusion where the smaller the molecular size is, the higher the diffusion rate.
