When a nonvolatile solute is added to a volatile solvent the boiling point?
When a solute is added to a solvent, the vapour pressure of the solvent (above the resulting solution) is lower than the vapour pressure above the pure solvent and addition of a non-volatile solute to a volatile solvent increase the boiling point this principle is known as boiling point elevation.

When a non-volatile solute is added to solvent its vapor pressure?
Solution : When a non-volatile solute is added to a solvent its vapour pressure decreases because some of the surface sites are occupied by solute molecules. Thus, less space is availabe for the solvent molecule to vaporise.

When a nonvolatile solute is added to a solvent it is freezing point will be?
When a non-volatile solute is added to the solvent, then vapour pressure of the solution decreases. A solute-solvent equilibrium exists at a lower temperature than the freezing point of pure solvent. As a result, the freezing point of the solution is lowered.

Why does adding a volatile solute to a solvent lower its vapour pressure?
When a solute is dissolved in a solvent, the number of solvent molecules near the surface decreases and the vapor pressure of the solvent decreases. The tendency of the water molecules to evaporate in the gas phase decreases. Thus the above statement is true.

Does adding a volatile solute increase vapor pressure?
A volatile solute increases the vapor pressure of the solution or will easily evaporate out of the solution. A nonvolatile solute does not add to the vapor pressure of the solution.

When non-volatile solute is added to solvent the vapour pressure of the solution decreases?
When we add a non-volatile solute to a solvent, the vapour pressure of the solution decreases because the surface area is partly occupied by non-volatile solute molecules and the rest by the solvent molecules. This lowers the rate of evaporation.

When a nonvolatile solute is added to a solvent What is the difference in vapour pressure expressed as a fraction of original vapour pressure equal to?
When a non-volatile solute is added to a solvent what is the difference in vapor pressure expressed as a faction of original vapor pressure equal to? Therefore, ΔP1/P1 = X2 which implies the relative lowering is equal to mole fraction of solute in liquid phase.
