WebLPG Calculator Calculate the vapor pressure and density of any blend of Propane, Isobutane, n-Butane, or Pentanes between the temperatures of -40 and 130F. At the same time, the rate at which water molecules in the vapor phase collide with the surface and reenter the solution is unaffected. Chemistry. The relationship between solution composition and vapor pressure is therefore, \[ \color{red} P_A=X_AP^0_A \label{13.6.1}\], where $P_A$ is the vapor pressure of component A of the solution (in this case the solvent), XA is the mole fraction of A in solution, and $P^0_A$ is the vapor pressure of pure A.

In a solution of $CCl_4$ and methanol, for example, the nonpolar $CCl_4$ molecules interrupt the extensive hydrogen bonding network in methanol, and the lighter methanol molecules have weaker London dispersion forces than the heavier $CCl_4$ molecules. This kind of behavior is called a negative deviation from Raoults law. At an ambient pressure of 25 degrees Celsius, the vapor pressure of water is 23.8 torr. The result is a higher vapor pressure than expected for an ideal solution, producing a positive deviation from Raoults law.
