Which among the following has rate of effusion less than the moist air?
Options:
Answer:
D
Solution:
Rate of effusion ∝ 1/√(M). Moist air (M ≈ 28.6) is lighter than dry air (M ≈ 29) because H₂O (18) displaces heavier N₂/O₂. He (4), NH₃ (17) and CH₄ (16) are all lighter and effuse faster; only dry air is heavier and effuses more slowly. Confirms Ans: (d) Dry air.
