equilibrium vapour pressure

According to the Le Chatelier's principle, this will make the system move in a direction of lower volume. An increase in pressure on the system will result in the condensation of vapours to give liquid, since, liquids have lower volume as compared to vapours. The ..

Vapour Pressure of Liquids - Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperature. fig 3.3 In illustrations 1a and 1b, the liquid and vapor stat..

Liquid-Gas (vapour) Equilibrium - When a liquid is placed in an open container it disappears completely after some time. However, when the same liquid is placed in a closed container, even after a long period only a part of the liquid disappears. The obvious difference is that t..

When substances get sublimated,the solid gets converted into vapour without passing through the liquid phase.Sublimation thus involves solid vapour equilibrium. On cooling the vapours, the solid is given back. This equilibrium is obtained in closed ..

Equilibrium between a liquid and its vapours can be represented by the equation...

Vapour density is the ratio of the mass of a volume of a gas, to the mass of an equal volume of hydrogen, measured under the same conditions of temperature and pressure. According to Avogadro's law, equal volumes of all gases contain equal number of molecules. Thus, let the n..

Solubility of a gas in a liquid increases with the increase in partial pressure of the gas above the solution. Quantitatively, this is governed by Henrys law, which states that at constant temperature. The mass of a gas dissolved in a given volume of the liquid is directly proportional ..

Equilibrium and its Dynamic Nature - The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as h..

In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed as: In this reaction, the products cannot ..
