rate of diffusion
affected by a number
of factors
factor Reason
The The greater the difference
concentration in concentration, the quicker
gradient the rate of diffusion.
The The higher the temperature,
particles (molecules & ions) temperature the more kinetic energy the
in a liquid and a particles will have, so they
gas move continuously will move + mix quicker
↳ because of this movement, The surface The greater the surface
particles will spread area of the area,the faster the rate
themselves evenly throughout cell membrane of diffusion.
- particles will move in separating
both directions a liquid or gas the different
regions
↳ BUT there will be a net
movement from high to
low concentration.
- will end up evenly spread Diffusion-when particles of
throughout the liquid or gas
↳ But will continue to a substance are in a higher concentration,
move they will move from this region to where
they are in lower concentration.
