Assertion: At high altitude, the ratio of nitrogen to oxygen in the atmosphere is larger than at sea level.
Reason: Lighter molecules have a larger scale height , so their concentration falls off more slowly with height.
Options:
Answer:
A
Solution:
Concentration varies as . Nitrogen (M = 28) falls more slowly than oxygen (M = 32), so its share grows with height. The reason explains the assertion. A.
