Pages 2. Click here to review vapor pressure of pure liquids and solids. That is what’s causing this vapor pressure lowering. Note: Larger n-alkane molecules have lower Po due to greater polarizability and hence increased strength of London Dispersion intermolecular forces. Find the equilibrium pressure and temperature for a monolayer of absorbed hydrogen on a mesoporous carbon storage material. –The effect is simply due to fewer solvent molecules at the solution’s surface. This video is highly rated by Class 12 students and has been viewed 551 times. Vapor pressure of a liquid is a colligative property. A high vapor pressure usually is an indication of a volatile liquid, or one that readily vaporizes. This pressure P is called the saturated vapor pressure. The only requirement is that the solute only dissolved and does not undergo a chemical reaction with the solvent. Vapour pressure is the pressure exerted by the vapours over the liquid under the equilibrium conditions at a given temperature. CH12 PPT 5 PHYSICAL PROPERTIES OF SOLUTIONS Refer pg:513 Chang Vapor pressure of H2O at a temperature is 20mmHg. Why is the vapor pressure lower? Presentation Summary : Vapor Pressure.
