Gas A and Gas B are both mixtures separated by a permeable membrane. Gas A contains 40% nitrogen at a partial pressure of 300 mm Hg. Gas B contains 80% nitrogen at partial pressure of 200 mm Hg. Given this information, in which direction do you expect to see a net movement of nitrogen and why?

Gas A is 40% oxygen and 10% CO2. It has a total pressure of 500 mm Hg. Gas A is in contact with a with a liquid containing oxygen at a partial pressure of 100 mmHg and CO2 at a partial pressure of 25 mm Hg. In which direction will O2 and CO2 diffuse in this situation?
