Fill in the blanks!
the freezing point of a solution will and the vapor pressure will with molality of a nonvolatile solute.
a.) increase, decrease, decreasing
b.) increase, increase, decreasing
c.) decrease, increase, decreasing
d.) decrease, increase, increase

B.Increase,increase,decreasing

Explanation:

Freezing point:It is defined as the temperature at which the substance freeze.

Vapor pressure: it is defined as the pressure exert by the vapor on the liquid at given temperature and pressure.

Molality:It is defined as the number of moles of solute dissolve in given mass of solvent.

When we decrease the freezing point of solution then depression in freezing point increase and then molality of nonvolatile solute is  also increase.

When we increase the molality of non volatile solute then elevation in boiling point also increase  and then vapour pressure decrease .

If we decrease molality then elevation in boiling point  and depression in freezing point also decrease.

If elevation in boiling point decrease then vapour pressure increase.

When depression in freezing point decrease then freezing point of solution is increase.

B.Increase,increase,decreasing

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
