Yes, nonvolatile solute lowers the vapor pressure and increases the boiling point. For instance, salt is an example of an nonvolatile solute in water. Ever wonder why salt is used in icy roadways in the winter? Because salt help inhibit the crystallization of water particles into ice by lowering the freezing point.

Explain why vapor pressure is reduced in a solution with a nonvolatile solute?
I have researched the Internet on your behalf and found a web site that appears to address your question. The link to the web site is called RAOULT'S LAW AND NON-VOLATILE SOLUTES and is displayed directly below this window.
An aqueous solution containing a nonvolatile solute will boil above 100 celsius at 1 ATM pressure true or false?
True. The addition of a nonvolatile solute to a solvent increases the boiling point of the solution compared to the pure solvent. This is known as boiling point elevation, and it occurs due to the decrease in vapor pressure of the solution.
What happens to a solvent when a nonvolatile solute is added to it?
It increases the boiling point of the solution and it increases the temperature range over which the solution remains a liquid.
A reduction of vapor pressure occurs with the addition of a nonvolatile solute to a solvent because?
There are fewer solvent molecules at the surface that can evaporate.

A solution containing all the solute that a solvent can dissolve at a certain temperature and pressure is called a saturated solution.

Doubling the amount of a nonvolatile solute in a solution?
A. doubles the elevation change of the boiling point
What happens if you double the nonvolatile solute in a solution?
doubles the elevation change of the boling point
Explain why the vapor pressure boiling point and freezing point of an aqueous solution if a nonvolatile solute are not the same as those of the pure solvent?
The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.
Adding a nonvolatile solute to water raises the blank and lowers the blank of the solution?

Is increase of vapor pressure a colligative property?
Yes, an increase in vapor pressure is a colligative property. Colligative properties depend on the number of solute particles in a solution, not their identity. Therefore, increasing the concentration of a solute in a solution will result in an increase in vapor pressure due to reduced effective solute-solvent interactions.

It increases the boiling point of the solution and it increases the temperature range over which the solution remains a liquid.

How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
The solute molecules mixed with the solvent molecules in a solution cause the of a solution to be higher than it is for an equal volume of pure solvent?
Raoult's Law and Vapor Pressure LoweringWhen a nonvolatile solute is added to a liquid to form a solution, the vapor pressure above that solution decreases. To understand why that might occur, let's analyze the vaporization process of the pure solvent then do the same for a solution. Liquid molecules at the surface of a liquid can escape to the gas phase when they have a sufficient amount of energy to break free of the liquid's intermolecular forces. That vaporization process is reversible. Gaseous molecules coming into contact with the surface of a liquid can be trapped by intermolecular forces in the liquid. Eventually the rate of escape will equal the rate of capture to establish a constant, equilibrium vapor pressure above the pure liquid.If we add a nonvolatile solute to that liquid, the amount of surface area available for the escaping solvent molecules is reduced because some of that area is occupied by solute particles. Therefore, the solvent molecules will have a lower probability to escape the solution than the pure solvent. That fact is reflected in the lower vapor pressure for a solution relative to the pure solvent. That statement is only true if the solvent is nonvolatile. If the solute has its own vapor pressure, then the vapor pressure of the solution may be greater than the vapor pressure of the solvent.Note that we did not need to identify the nature of the solvent or the solute (except for its lack of volatility) to derive that the vapor pressure should be lower for a solution relative to the pure solvent. That is what makes vapor pressure lowering a colligative property--it only depends on the number of dissolved solute particles.summarizes our discussion so far. On the surface of the pure solvent (shown on the left) there are more solvent molecules at the surface than in the right-hand solution flask. Therefore, it is more likely that solvent molecules escape into the gas phase on the left than on the right. Therefore, the solution should have a lower vapor pressure than the pure solvent.Figure %: The Vapor Pressure of a Solution is Lower than that of the Pure Solvent
What is the difference between solution and concentrared solution?
A solution is a solute dissolved in a solvent. A concentrated solution is all the solute that be dissolved in a solvent at normal temperature. A super-concentrated solution is all the solute that can be dissolved in a solution after mixing in the solute during high temperature / pressure. The concentration after cooling to normal temperature / pressure is greater than a regular concentrated solution.
