The Equilibrium Vapor Pressure Of A Liquid Is

It relates to the tendency of particles to escape from the liquid or a solid. It is the pressure of a gaseous state when it is in equilibrium with the condensed liquid or solid phase step 2 in case of vapor pressure of liquid as the temperature increases the kinetic energy of the liquid molecules increases.

Vapor Pressure Wikipedia

Vapor pressure is the gas pressure exerted when a material is in equilibrium with its own vapor atoms escape at the same rate as the atoms re condense on the material surface.

The equilibrium vapor pressure of a liquid is. The equilibrium vapor pressure is an indication of the evaporation rate of a liquid. The pressure exerted by a vapor in dynamic equilibrium with a liquid is the equilibrium vapor pressure of the liquid. The equilibrium vapor pressure is an indication of a liquid s evaporation rate.

Sintering of advanced materials 2010. The equilibrium vapour pressure of a liquid also usually called the saturated vapour pressure svpof a vapour is the partial pressure of the vapour phase when the vapour and liquid phases are in. In thermodynamics and chemical engineering the vapor liquid equilibrium vle describes the distribution of a chemical species between the vapor phase and a liquid phase.

If a liquid is in an open container however most of the molecules that escape into the vapor phase will not collide with the surface of the liquid and return to the liquid phase. The concentration of a vapor in contact with its liquid especially at equilibrium is often expressed in terms of vapor pressure which will be a partial pressure a part of the total gas pressure if any other gas es are present with the vapor. P pressure at equilibrium p m s saturation pressure of the mixture p i s saturation pressure of component i note.

The vapor pressure of a liquid is the equilibrium pressure of a vapor above its liquid or solid. A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor that is in thermodynamic equilibrium with the condensed phase solid or liquid at a given temperature in a closed system.

It is assumed that the mixture is maintained at equilibrium thus the pressure above the liquid is equal to the. That is the pressure of the vapor resulting from evaporation of a liquid or solid above a sample of the liquid or solid in a closed container. The pressure exhibited by vapor present above a liquid surface is known as vapor pressure.

It is a function of the temperature x i molar fraction of the component in the liquid phase.
