Raoult's law is a law of thermodynamics established by French chemist François-Marie Raoult in 1887. It states that the partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapour pressure of the pure component multiplied by its mole fraction in the mixture. In consequence, the relative lowering of vapour pressure of a dilute solution of nonvolatile solute is equal to the mole fraction of solute in the solution.
where is the partial pressure of the component in the gaseous mixture (above the solution),is the vapor pressure of the pure component and is the mole fractionof the component in the mixture (in the solution).
Once the components in the solution have reached equilibrium, the total vapor pressure of the solution can be determined by combining Raoult's law with Dalton's law of partial pressures to give
If a non-volatile solute (zero vapor pressure, does not evaporate) is dissolved into a solvent to form an ideal solution, the vapor pressure of the final solution will be lower than that of the solvent. The decrease in vapor pressure is directly proportional to the mole fraction of solute in an ideal solution.

In the year 1919 the British government passed in new rule called Rowlatt Act ,under which the government had the authority and power to arrest people and give them without any trial.
Mahatma Gandhi was extremely agitated by enactment of Rowlatt Act . He was extremely critical about the act and argued that everyone could not be punished for isolated political crime.
