van't Hoff, Jacobus Henricus

(vant-hof′) Dutch physical chemist, 1852–1911

van't Hoff law

The osmotic pressure of a solution is equal to the product of its temperature, the ideal gas constant, and its solute concentration.

van't Hoff rule

1. The rule that the speed of chemical reactions is doubled, at least, for each 10°C rise in temperature. The rule is an approximation that works best when temperatures approximate those under which the reaction normally occurs. 2. Any substance in a dilute solution exerts an osmotic pressure that is equivalent to the pressure of an equal volume of gas in solution.3. A technique used to predict the greatest number of mirror-image versions of a molecule that can rotate plane polarized light.
