Solutions Question 247
Question: Molar solubility of helium, nitrogen and oxygen are plotted against partial pressure of the gas at constant temperature. Henry’s law constant for hese gases will lie in the following sequence-
Options:
A) $ O_2>N_2>He $
B) $ O_2<N_2<He $
C) $ O_2=N_2=He $
D) $ O_2>N_2>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.
