Evaporation or vaporization. Molecules from a liquid or solid continually escape the surface to become gas molecules. Condensation. This is the opposite process where the gas molecules strike an and stick to the surface of the liquid or gas. At equilibrium the rate of evaporation and condensation are equal.

The four state symbols show the physical state of substances at normal conditions Symbol equations should be included when writing chemical equations. An example of a reaction with state symbols is the reaction of copper carbonate with hydrochloric acid:

r It should be noted that K° as defined above must be a pure number. In this respect it may differ from equilibrium constants differently defined. In gas-phase equilibria, for instance, the "fugacity' equilibrium constant, K,, which has the dimension of [fugacity] , is only a pure number when BVB happens to be zero. (Here B' refers to all the speci...
