Vapor Pressure

High VP = eq shifts rightLow VP = eq shifts left

Page 4: Liquid-Vapor Equilibrium HL. Vapor Pressure Vapor pressure- the pressure of the vapor as a result of evaporation in a closed container

Vapor Pressure

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