Liquid-Vapor Equilibrium HL

Vapor Pressure

Vapor pressure- the pressure of the vapor as a result of evaporation in a closed container

Vapor Pressure

High VP = eq shifts rightLow VP = eq shifts left

Vapor Pressure

Equilibrium will be reached quicker when surface area is increased, but the equilibrium position will not change and VP remains the same.

Vapor Pressure

Vapor Pressure

(This increasesVP and Keq as well!)

Important!

Vapor Pressure

External pressure = atmospheric pressure

Very important!!!

Vapor Pressure

The higher the temperature and the weaker the imf’s, the higher the vapor pressure
