Answer 1

Answer:

The correct answer is the greater for gases with lower solubility.

Explanation:

According to the Henry's constant law,

$P=K_HX$ and $K_H\alpha \frac{1}{X}$

Where, P=Partial pressure of gas

X= solubility of gas in liquid

$K_{H}$= Henry's constant

For the highly soluble gas, value of the $K_{H$is very less for the gas and in's solubility is also gets lower with $K_{H$ is vey high.

Thus, the answer is the (ii)greater for gases with lower solubility.
