In chemistry, Le Chatelier's principle (pronounced UK: / l ə ʃ æ ˈ t ɛ l j eɪ / or US: / ˈ ʃ ɑː t əl j eɪ /) [1] is a principle used to predict the effect of a change in conditions on chemical equilibrium. [2] Other names include Chatelier's principle, Braun–Le Chatelier principle, Le Chatelier–Braun principle or the equilibrium ...
Henry Louis Le Chatelier [1] (French pronunciation: [ɑ̃ʁi lwi lə ʃɑtəlje]; 8 October 1850 – 17 September 1936) was a French chemist of the late 19th and early 20th centuries. He devised Le Chatelier's principle, used by chemists and chemical engineers to predict the effect a changing condition has on a system in chemical equilibrium.
Its solubility in pure water is 7.32 x 10 −4 M. However in a solution that is 0.0200 M in barium nitrate, Ba(NO 3) 2, the increase in the common ion barium leads to a decrease in iodate ion concentration. The solubility is therefore reduced to 1.40 x 10 −4 M, about five times smaller. [1]
In the blood of most animals, the bicarbonate buffer system is coupled to the lungs via respiratory compensation, the process by which the rate and/or depth of breathing changes to compensate for changes in the blood concentration of CO 2. [10] By Le Chatelier's principle, the release of CO 2 from the lungs pushes the reaction above to the left ...
Le Chatelier can refer to: Alfred Le Chatelier (1855–1929), French soldier, explorer and professor; Bénédicte Le Chatelier (born 1976), French television journalist; Henry Louis Le Chatelier, 19th-century chemist Le Châtelier's principle, named after Henry Louis Le Chatelier; Louis Le Chatelier, 19th-century chemist and industrialist ...
Louis Le Chatelier (20 February 1815 – 10 November 1873) was a French chemist and industrialist who developed a method for producing aluminium from bauxite in 1855. His son was chemist Henry Louis Le Chatelier. His name is inscribed on the Eiffel tower. [1] [2]
Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics.
According to the thermal flame theory of Ernest-François Mallard and Le Chatelier, the un-stretched laminar flame speed is dependent on only three properties of a chemical mixture: the thermal diffusivity of the mixture, the reaction rate of the mixture and the temperature through the flame zone:
