As the concentration of a solute in a solution increases, the freezing point of the solution
And the vapor pressure of the solution .
A) decreases, increases
B) decreases, is unaffected
C) increases, increases
D) decreases, decreases
E) increases, decreases

Question

Quizplus · Accepted Answer

The freezing point of a solution decreases as the concentration of a solute increases due to freezing point depression. The vapor pressure of the solution also decreases because the presence of solute particles reduces the number of solvent molecules at the surface, lowering the vapor pressure.
