Gas X and gas Y have Henry's law constants KH=2kbar and 40kbar respectively in water at 298K (law written as p=KHx). At the same partial pressure and temperature, which statement is correct?
AThe mole fraction of Y in solution is 20 times that of X
BX and Y dissolve to the same extent
CThe mole fraction of X in solution is 2 times that of Y
DThe mole fraction of X in solution is 20 times that of Y
Answer: D
From p=KHx, x=p/KH, so at equal p, x is inversely proportional to KH. xX/xY=40/2=20, so X is the more soluble gas.
