What is Raoult's Law of vapor-pressure? Could someone please explain with diagrams?

Raoult's law just says that the vapor pressure
For ideal mixtures (no change in intermolecular forces after mixing), it is based on the mole fraction
#P_A = chi_(A(l))P_A^"*"# where
#A# is the solvent.
Since
The solute blocks the solvent from vaporizing, so it is harder to boil, and thus the vapor pressure is lower than desired; it is harder to reach the atmospheric pressure, so the boiling point is also higher.
