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?

• A. From Gas A to Gas B because the total pressure of Gas A is greater than Gas B.
• B. From Gas B to Gas A because Gas B has a higher concentration of nitrogen than Gas A.
• C. From Gas B to Gas A because 80% of 200 mm Hg > 40% of 300 mm Hg.
• D. From Gas A to Gas B because the partial pressure of nitrogen in Gas A is greater than in Gas B.
