1
Q
Dalton’s law
A
In non reacting gases the pp is equal to them sum of the pp of the individual gases
2
Q
Ficks law
A
Diffusion will occur more rapidly when
- large difference in pp across a semi permeable membrane
- small distance
- large surface area
- temp increase
3
Q
What substance diffuses quickest?
A
Co2 diffuses through respiratory membranes 20 times more rapidly than O2
4
Q
Grahams law
A
Heavier gases should diffuse more slowly
5
