**According to Raoult's Law:**The partial pressure of any volatile component of a solution at any temperature is equal to the vapour pressure of the pure component multiplied by the mole fraction of that component in the solution.

Where X

_{A} and X_{B}is the mole fraction of the component A and B in liquid phase respectively**According to Dalton's Law:**

The vapour behaves like an ideal gas, then

**according to Dalton's law**of partial pressures, the total pressure P_{T}is given by: Partial pressure of the gas = Total pressure x Mole fraction

**P**

_{A}= P_{T}Y_{A}and P_{B}=P_{T}Y_{B}Where Y

_{A} and Y_{B}is the mole fraction of the component A and B in gas phase respectively**Combination of Raoult's and Dalton's Law:**

**(3)**Thus, in case of ideal solution the vapour phase is phase is richer with more volatile component i.e., the one having relatively greater vapour pressure

**Graph Between 1/Y**

_{A}Vs 1/X_{A}:**According to Dalton's law**of partial pressures, the total pressure P

_{T}is given by:

Partial pressure of the gas = Total pressure x Mole fraction

Where Y

_{A} and Y_{B}is the mole fraction of the component A and B in gas phase respectively**According to Raoult's law:**

On rearrangement of this equation we get a straight line equation:
