Adding a nonvolatile solute to a solution decreases the vapor pressure of the solution. True or False

True.

Explanation:

Adding a non - volatile solute to solvent, decreases the tendency for water molecules to evaporate into gas phase i.e these non - volatile solute particles obstruct or reduce the rate of evaporation. Few water molecules in the vapour.

Therefore, Adding a nonvolatile solute to a solution decreases the vapor pressure of the solution while

Vapor pressure is a measurement of the likelihood of the molecules of a pure solvent to change from the liquid to the vapor phase.

Using Raoult's Law:

Psol = Xsolv * P°solv

where:

Psol = the vapor pressure of the solvent above the solution,

Xsolv = the mole fraction of the solvent in the solution, and

P°solv = the vapor pressure of the pure solvent.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
