Interpretation:
The given below expression has to be proved.
Where,
Concept Introduction:
Raoult’s law:
It states that the equilibrium vapor pressure of the solvent over a solution is directly proportional to the mole fraction of the solvent in the solution.
The expression for the vapor pressure lowering is given below.
Where,
Dalton’s law of partial pressure:
According to Dalton’s law of partial pressure, the total pressure of a mixture is the sum of partial pressures each component.
The partial pressure of each component can also be represented as given below.’
Therefore, the total pressure of the mixture is given below.
