Identify the law which is stated as "For any solutions, the partial vapour pressure of each volatile component in the solution is directly proportional to its mole fraction".

Step-by-step solution

Raoult's law states that for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in solution. p_i x_i p_i = p_i^0 x_i Gay-Lussac's law relates the pressure and temperature of a fixed mass of gas at constant volume. Dalton's law states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of individual gases. Henry's law states that the partial pressure of the gas
