Activity coefficient — An activity coefficient [ [http://www.iupac.org/goldbook/A00116.pdf Gold Book definition] ] is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances. In an ideal mixture the… … Wikipedia
Activity (chemistry) — In chemical thermodynamics, activity (symbol a) is a measure of the “effective concentration” of a species in a mixture, meaning that the species chemical potential depends on the activity of a real solution in the same way that it would depend… … Wikipedia
activity — 1. In electroencephalography, the presence of neurogenic electrical energy. 2. In physical chemistry, an ideal concentration for which the law of mass action will apply perfectly; the ratio of the a. to the true concentr … Medical dictionary
coefficient — 1. The expression of the amount or degree of any quality possessed by a substance, or of the degree of physical or chemical change normally occurring in that substance under stated conditions. 2. The ratio or factor that relates a quantity… … Medical dictionary
Osmotic coefficient — An osmotic coefficient φ is a quantity which characterises the deviation of a solvent from ideal behaviour, referenced to Raoult s law. The osmotic coefficient on a molality basis is defined by:[1] and on an amount fraction basis by: where is the … Wikipedia
Water activity — or aw is a measurement of the energy status of the water in a system. It is defined as the vapor pressure of water above a sample divided by that of pure water at the same temperature; therefore, pure distilled water has a water activity of… … Wikipedia
Partition coefficient — In chemistry and the pharmaceutical sciences, a partition (P) or distribution coefficient (D) is the ratio of concentrations of a compound in the two phases of a mixture of two immiscible solvents at equilibrium.[1] The terms gas/liquid partition … Wikipedia
