van't Hoff law
Pronunciation: vahnt hof
- in stereochemistry, all optically active substances have one or more multivalent atoms united to four different atoms or radicals so as to form in space an asymmetric arrangement;
- the osmotic pressure exerted by any substance in dilute solution is the same that it would exert if present as gas in the same volume as that of the solution; or, at constant temperature, the osmotic pressure of dilute solutions is proportional to the concentration (number of molecules) of the dissolved substance; the osmotic pressure, ?, in dilute solutions is ? = RTSci, where R is the universal gas constant, T is the absolute temperature, and ci is the molar concentration of solute i;
- the rate of chemical reactions increases between two- and threefold for each 10°C rise in temperature.
