Le Chatelier's principle
Videos
In chemistry, Le Chatelier's principle is a principle used to predict the effect of a change in conditions on chemical equilibrium. Other names include Chatelier's principle, Braun–Le Chatelier princi
The reversible reaction 2NO2(g) ⇌ N2O4(g) is exothermic, so the equilibrium position can be shifted by changing the temperature. When heat is removed and the temperature decreases, the reaction shifts to the right and the flask turns colorless due to an increase in N2O4. This demonstrates Le Chatelier's principle: the equilibrium shifts in the direction that releases energy. When heat is added and the temperature increases, the reaction shifts to the left and the flask turns reddish brown due to an increase in NO
Haber process

The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. It converts atmospheric nitrogen to ammonia by a reaction with hydrogen using fi
Le Chatelier's principle
…would be produced if the reaction were run at a lower temperature, but a lower temperature also lowers the rate of the process, so, in practice (the Haber process) the temperature is set at a compromise value that allows ammonia to be made at a reasonable rate with an equilibrium concentration that is not too…

A historical (1921) high-pressure steel reactor for the production of ammonia via the Haber process is displayed at the Karlsruhe Institute of Technology, Germany.
