Posted in: Law Commons 7 hours ago Why Raoult's Law works. If you look review the concepts of colligative properties, you will find that adding a solute lowers vapor pressure because the additional solute particles will fill the gaps between the solvent particles and take up space. This means less of the solvent will be on the surface and less will be able to break free to enter the gas phase, resulting in a lower vapor pressure.

Posted in: Law Commons 4 hours ago Raoult’s Law. Raoult’s law has been named after François-Marie Raoult, a French chemist who while conducting an experiment found out that when substances were mixed in a solution, the vapour pressure of the solution decreased simultaneously.

1. The pressure at which vapor is formed above a solid or liquid at a particular temperature is called the vapor pressure. Vapor and solid or liquid are in dynamic equilibrium at this temperature. In 1980s Rault discovered when a non-volatile solute is dissolved in a solvent the vapor pressure decreases. The lowering of vapor pressure depends on the mole fraction of the solute dissolved and the vapor pressure of the pure solvent. Thus the Rault’s stated as the relative lowering of vapor pressure of a dilute solution containing non-volatile solute is equal to the mole fraction of that solute and the vapor pressure of the pure solvent.

### How do you use Raoult's law?

Raoult's Law can be used to express the vapor pressure relationships of solutions containing both volatile and nonvolatile solvents. When two or more volatile solutions are mixed, each pressure component of the mixed solution is added together to find the total vapor pressure. P Total = P solution A + P solution B + ...

### What is the difference between Henry's Law and Raoult's law?

Henry's law and Raoult's law generally are associated with the vapor pressures of the pure solution, of the solution with stuff in it, and of the mole fraction of stuff in the would-be pure solution. Henry's law works best at low concentration of the solute (close to 5% or less).

### What is the effect of Raoult's law on idea solutions?

Suppose A and B are the molecule of solvent and solute. So, If ϒ AB = ϒ AA, the solution will obey the Raoult’s law. Thus it is an idea solution. But if ϒ AB < ϒ AA, then the molecule will escape more readily than the pure solvent. The vapour pressure of the solution will be higher and positive deviation from Raoult’s law will be observed.

### Is Raoult's law valid for a concentrated solution?

Note: Although the Raoult's law is valid for diluted (ideal) solution, its application to concentrated (non-ideal) solutions does not lead to variation of the order of magnitude of the calculated vapor pressure. 2.
