Solutions Question 162
Which one of the following gases has the lowest value of Henry’s law constant
Options:
A) $ N_2 $
He
C) $ H_2 $
D) $ CO_2 $
Show Answer
Answer:
Correct Answer: D
Solution:
According to Henry’s law the mass of a gas dissolved per unit volume of solvent is proportional to the pressure of the gas at constant temperature m = Kp i.e. as the solubility increases, value of Henry’s law constant increases. Since $ CO_2 $ is most soluble in water among the given set of gases. Therefore $ CO_2 $ has the highest value of Henry’s law constant.
