Question 9

each gas in a mixture of gases exerts its own pressure as if no other gases were present; each gas diffuses across a permeable membrane from the area where its partial pressure is greater to the area where its partial pressure is less[THE GREATER THE DIFF, THE FASTER THE RATE OF DIFFUSION]
