Question

osmotic pressure of a solution is directly proportional to the solute concentration .....then why diffusion pressure of a solution is not proportional to the solute concentration​

Answer 1

Answer:

osmosis is done when semi permeable membrane is present....

so concentration of solute is dependent

that how much amount of solute is pass through semi permeable membrane

diffusion not required membrane...

this is the major difference between them.....

Answer 2

Answer:

as,

π=CRT

from above we can say that,

The molecular concentration of solute

The absolute temperature at a given concentration

The lowering of vapour pressure as it is colligative property and depends on no of the molecule.
