Solutions Question 74

Question: Molar solubility of helium, nitrogen and oxygen are plotted against partial pressure of the gas at constant temperature. Henry’s law constant for these gases will lie in the following sequence-

Options:

A) $ O_2 \gt N_2 \gt He $

B) $ O_2 \lt N_2 \lt He $

C) $ O_2=N_2=He $

D) $ O_2 \gt N_2 \gt He $

Show Answer

Answer:

Correct Answer: B

Solution:

Gas Temperature $ K_{H} $ (K bar) $ He $ 293 144.97 $ N_2 $ 293 76.48 $ O_2 $ 293 34.86 The higher the value of Henry-s law constant, the lower is the solubility of the gas in the liquid.
