Differbetween
The key difference between Raoult law and Dalton law is that Raoult law deals with the vapour pressure of solids or liquids, whereas Dalton law deals with the partial pressure of non-reacting gases. Raoult law and Dalton law are very important laws in chemistry that explain the partial pressures of gaseous states.

What is Dalton's Law of distillation?
Dalton's law of partial pressures states that the total pressure in a closed system can be found by addition of the partial pressures of each gaseous component. ... This combined law shows that the vapors produced by distillation are dependent on each component's vapor pressure and quantity (mole fraction).
What is meant by Raoult's Law?
Raoult's law states that the vapor pressure of a solvent above a solution is equal to the vapor pressure of the pure solvent at the same temperature scaled by the mole fraction of the solvent present: Psolution=χsolventPosolvent.
What is the similarity between Raoults law and Henry Law?
Similarity between Raoult's law and Henry's law: Both laws state that the partial pressure of the volatile component is directly proportional to its mole fraction in the solution. In case of Roult's law it is liquid and in case of Henry's law it is gas.
Why is Dalton's law a limiting law?
Limitation of Dalton's Law
The law holds good for real gases at low pressure, but at high pressure, it deviates significantly. The mixture of gases is non-reactive in nature. It is also assumed that the interaction among the molecules of each individual gas is the same as the molecules in the mixture.
What does Daltons law state?
Dalton's law, the statement that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual component gases. The partial pressure is the pressure that each gas would exert if it alone occupied the volume of the mixture at the same temperature.
What is Dalton's law used for?
Dalton's law of partial pressures is used to determine the individual pressures of each gas in a mixture of gases.
In which case Raoult's Law is not applicable?
Note: Raoult's law cannot be applied in the cases where the total number of particles of solute changes in solution due to association or dissociation. When a substance is dissolved in a solution if it ionizes to its constituents ions, it is dissociation.
What is Raoult's Law derive it mathematically?
Raoult's law states that a solvent's partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution. Mathematically, Raoult's law equation is written as; Psolution = ΧsolventP0solvent.
Which has maximum Vapour pressure?
Solution : Because HCI has the minimum boiling points.
What is meant by positive deviation from Raoult's Law?
Positive deviation from Raoult's law means when the vapour pressure is higher than the solution is expected to exhibit. An example of positive deviation from Raoult's law is the mixture of acetone and ethanol.
What is a limiting law?
Limit Laws are the properties of limit. They are used to calculate the limit of a function. Constant Law. The limit of a constant is the constant itself.
How is Dalton's law calculated?
Dalton's law states that: the total pressure exerted on a container's walls by a gas mixture is equal to the sum of the partial pressures of each separate gas. It can also be illustrated with an equation: total pressure = p1 + p2 + ...
What is r in PV nRT?
PV = nRT. The factor “R” in the ideal gas law equation is known as the “gas constant”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number.
