Rate of diffusion?

Question

name 5 factors affecting the rate of diffusion

Answer 1

1. temperature

2. thickness of exchange surface

3. concentration of substance

4. size of molecules

5. charge of molecules

6. shape of molecules (i.e. molecules with branches such as starch would take longer than glucose for instance)

Answer 2

the factors which affect the diffusion rate are:

1) Gradient (difference in concentration of two environments) [more gradient-higher rate]

2) Temperature (more temp-higher rate)

3) Size of the molecules [the smaller the particles-the higher is the rate]

Answer 3

1. te,mperature

2. size of the molecule

3. medium in which diffusion is occurring

gotta go, sorry
