Diffusion is the passive net movement of particles from a region of high concentration to an area of low concentration. It will continue until there is a concentration equilibrium between the two areas.

Simple diffusion: Diffusion in the absence of a barrier. (no barrier present)

Factors affecting the rate:

  • Temperature- higher temp the particles will have more kinetic energy, will diffuse faster.
  • Concentration difference- the greater the difference between the two areas the faster the particles will move.

Diffusion accross a mambrane:

  • Involves particles moving across a permeable membrane.
