I think I know what your problem is..
Explanation:
Raoult's law indeed states that the partial pressure of a gas varies directly as its mole fraction,
where
-
Pa is the partial pressure of componenta of the gaseous mixture (which is above the solution), -
χa is the mole fraction ofa in the solution, and -
Pa is the pure vapor pressure ofa
(This is a result of the colligative property called vapor-pressure lowering)
In your problem, it said that as concentration increases, the mole fraction increases, and the partial pressure decreases. The
This may have been a result of confusion, but
That is,
