The law may be stated: [3] At the age of 19, after only one year of instruction in specialized engineering, he followed in his father’s footsteps by enrolling in the École Polytechnique on 25 October 1869. We have discussed some of the mathematical relationships … Le Châtelier blev født den 8. oktober 1850 ved den fransk-italienske grænse af forældrene Louis Le Châtelier og Louise Durand. Le Châtelier was born on 8 October 1850 in Paris and was the son of French materials engineer Louis Le Châtelier and Louise Durand. He successfully introduced his ideas about industrial science to the Société d’Encouragement pour l’Industrie Nationale as guidelines for research programs initiated by the institution. In 1904 he founded and edited the Revue de métallurgie, which became a medium for his ideas on industrial science. His results on chemical equilibrium were presented in 1885 at the Académie des sciences in Paris. Henri Louis Le Châtelier (8 October 1850 - 17 September 1936) was an influential French chemist of the late 19th and early 20th centuries. In an interesting twist, the French scientist who developed it — Henry Louis Le Chatelier — dabbled in ammonia production at one point in his long and notable career. Henri Louis had one sister (Marie) and four brothers (Louis (1853–1928), Alfred (1855–1929), G… Le Châtelier became a well-known industrial chemist himself, interested in metallurgy, cements, glasses, fuels, explosives, and, most famously, chemical equilibrium.

Henry Louis Le Châtelier (født 8. oktober 1850, død 17. september 1936) var en fransk/italiensk kemiker, som har bidraget afgørende til forståelsen af kemisk ligevægt formuleret som Le Chateliers princip.. Biografi. Le Chatelier found that the explosion was due to the presence of air in the apparatus used. Henry Louis Le Chatelier : biography 8 October 1850 – 17 September 1936 Le Chatelier in 1901 attempted the direct combination of the two gases nitrogen and hydrogen at a pressure of 200 atm and 600⁰C in presence of metallic iron.

(París, 1850 - Miribel-les-Echelles, 1936) Químico francés conocido por el principio que lleva su nombre, que permite predecir los efectos originados por los cambios de ciertas condiciones (como la presión, la temperatura o la concentración de los reactivos) en una reacción química. He perfected the coupling of pure platinum with a platinum-rhodium alloy that gave rise to the thermoelectric pyrometer, known as the “Le Chatelier.” He also adapted an optic pyrometer for industrial use. Chatelier's Principle or the Equilibrium Law The principle is named for Henry Louis Le Chatelier. He suggested increasing the output of industrial ammonia production by using low heat and high pressure, as indicated by his principle of chemical equilibrium. Consequently, in 1899 Le Chatelier devoted a year to studying these issues, concluding with a translation of Gibb’s original work about chemical equilibrium systems. The following year, he entered the mining engineer program at the École des Mines in Paris, from which he graduated in 1873. Le Chatelier’s Principle states that a system always acts to oppose changes in chemical equilibrium; to restore equilibrium, the system will favor a chemical pathway to reduce or eliminate the disturbance so as to restabilize at thermodynamic equilibrium. He dedicated a large part of his last years to promoting the American engineer Frederick W. Taylor’s theories about the scientific organization of work. His family home was like a drop-in center for France's leading chemists. Iomraidhean. Henri-Louis Le Châtelier was born into a family of architects, engineers, and scientists in Paris. After two years in the provinces as a mining engineer, Le Chatelier returned to the École des Mines as a chemistry lecturer in 1877. Abstract Henry-Louis Le Châtelier (1850-1936) is a well-known name to all students of physical chemistry. Under the direction of the French mineralogist Ernest-François Mallard, Le Chatelier conducted experiments on explosive materials, which led him to improvements in measuring high temperatures, based on the thermocouple principle. He is most famous for devising Le Châtelier's principle, used by chemists to predict the effect a changing condition has on a system in chemical equilibrium. He had at his disposal a well-equipped laboratory that he put to good use the following year by contributing to the Firedamp Commission, which was concerned with the improvement of safety in mines. Le Chatelier and Karl Ferdinand Braun independently proposed the principle, which is also known as Chatelier's principle or the equilibrium law. Le Chatelier also was interested in hydraulic binding materials, such as e.g.
