Question

A solution containing a nonvolatile solute will have a(n) vapor pressure than the pure solvent. The change in the vapor pressure is proportional to the fraction of the solute in the solution.

Answer 1

A solution containing a nonvolatile solute will have a lower vapor pressure than the pure solvent and the change in vapor pressure is directly proportional to the fraction of the solute in the solution.

What happens to a liquid when a non-volatile solute is dissolved in it?

The addition of a nonvolatile solute to a liquid solvent results in a lowering of the vapor pressure of the solvent.

The change in the vapor pressure is directly proportional to the mole fraction of the solute in the solution.

Therefore, a solution containing a nonvolatile solute will have a lower vapor pressure than the pure solvent and the change in vapor pressure is directly proportional to the fraction of the solute in the solution.
