Octave Leopold Boudouard
Octave Leopold Boudouard (1872–1923) was a French chemist known for his 1905 discovery of the Boudouard reaction. Career Octave Leopold Boudouard became a professor at the Conservatoire National des Arts et Métiers in Paris. He worked in various fields of applied chemistry, such as the chemistry of fuels and clays. His most important work was his research into chemical equilibria when reducing iron oxides in a blast furnace. In 1901 he proposed the first theory of the hydrogenation of carbon monoxide, where he considered that metal oxide was reacting with carbon. In 1905 Boudouard identified the Boudouard reaction, where carbon and carbon dioxide combine to form carbon monoxide at high temperatures, while the reverse occurs at lower temperatures. In 1912 he published a paper on the odors of Paris, researching the chemicals polluting the air of that city.

Boudouard Reaction
The Boudouard reaction, named after Octave Leopold Boudouard, is the redox reaction of a chemical equilibrium mixture of carbon monoxide and carbon dioxide at a given temperature. It is the disproportionation of carbon monoxide into carbon dioxide and graphite or its reverse: ::2CO + C The Boudouard reaction to form carbon dioxide and carbon is exothermic at all temperatures. However, the standard enthalpy of the Boudouard reaction becomes less negative with increasing temperature, as shown to the side. While the formation enthalpy of is higher than that of , the formation entropy is much lower. Consequently, the standard free energy of formation of from its component elements is almost constant and independent of the temperature, while the free energy of formation of decreases with temperature. At high temperatures, the forward reaction becomes endergonic, favoring the (exergonic) reverse reaction toward CO, even though the forward reaction is still exothermic. The effec ...

Conservatoire National Des Arts Et Métiers
A music school is an educational institution specialized in the study, training, and research of music. Such an institution can also be known as a school of music, music academy, music faculty, college of music, music department (of a larger institution), conservatory, conservatorium or conservatoire ( , ). Instruction consists of training in the performance of musical instruments, singing, musical composition, conducting, musicianship, as well as academic and research fields such as musicology, music history and music theory. Music instruction can be provided within the compulsory general education system, or within specialized children's music schools such as the Purcell School. Elementary-school children can access music instruction also in after-school institutions such as music academies or music schools. In Venezuela El Sistema of youth orchestras provides free after-school instrumental instruction through music schools called ''núcleos''. The term "music school" can a ...

Bulletin De La Société Chimique De France
The ''Bulletin de la Société Chimique de France'' was a French peer-reviewed scientific journal on chemistry published by the Société Chimique de France. It was established in 1858 under the title ''Bulletin de la Société Chimique de Paris'' (), under which additional name it appeared until the end of series 3. The journal was published in several series: * ''Bulletin de la Société Chimique de France'' (), Vol. 1 (1858) – Vol. 6 (1863) (= 1. Ser.). * ''Bulletin de la Société Chimique de France, N.S.'' (= 2. Ser., Vol. 1 (1864) – Vol. 50 (1888), (ISSN 0037-8968). * ''Bulletin de la Société Chimique de France, 3. Ser.'', Vol. 1 (1889) – Vol. 36 (1906), (ISSN 0037-8968). * ''Bulletin de la Société Chimique de France, 4. Ser.'', Vol. 1 (1907) – Vol. 54 (1933). The fourth series of this journal was published as: * ''Bulletin de la Société Chimique de France, 4. Ser, Analyse des travaux étrangers'', Vol. 1 (1907) - Vol. 28 (1920), (). * ''Bulletin de la Sociétà ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1872 Births
Year 187 ( CLXXXVII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Quintius and Aelianus (or, less frequently, year 940 '' Ab urbe condita''). The denomination 187 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
