Which among the following has rate of effusion less than the moist air?
Options:
Answer:
B
Solution:
Rate of effusion ∝ 1/√(M). Moist air is lighter than dry air (H2O, M = 18, displaces N2/O2, M = 28/32), so dry air (M ≈ 29) is the only gas here heavier than moist air and hence effuses more slowly. He (4), NH3 (17) and D2 (4) are all lighter and effuse faster. Confirms Ans: (b) Dry air.
