If oxygen is moving between a liquid and a gas,which factor is the most important in determining the direction in which that oxygen will diffuse?

Question

Quizplus · Accepted Answer

Diffusion depends on the difference in partial pressure of the gas between the two phases. The direction of oxygen movement is from the area of higher partial pressure to the area of lower partial pressure. Concentration differences (choice A) and length/path of diffusion (choice B) do play a role, but the primary driving force is the difference in partial pressure (choice C). Volume of the liquid (choice D) and surface area of the liquid (choice E) can affect the rate of diffusion but not the direction of diffusion.
