 Henry law constant for two gases are 21.5 and 49.5 atm, which gas is more soluble ? 

Answer»

 KH is inversely proportional to solubility

As    S = kh × X

i.e. solubility = Henry constant × mole fraction

So, S is directly proportional to Kh.

Hence, higher the value of kh,  higher will be its S. Hence 49.5 is the answer .
