principio de Le Chatelier-Braun
- According to the Le Chatelier-Braun principle, when a change is made to the concentration of a reactant, the equilibrium will shift to reduce that change.
Examples
-
According to the Le Chatelier-Braun principle, increasing the temperature shifts the reaction equilibrium to favor the products.
-
When pressure is applied to a system at equilibrium, the Le Chatelier-Braun principle predicts how the system responds.
-
Students were asked to explain the Le Chatelier-Braun principle using examples from chemical industry processes.
-
The Le Chatelier-Braun principle explains how equilibrium shifts in response to changes.
-
According to the Le Chatelier-Braun principle, increasing temperature affects equilibrium.
-
The Le Chatelier-Braun principle illustrates how a chemical reaction will adjust to counteract changes in temperature or pressure.
-
Students learned that the Le Chatelier-Braun principle helps predict the shift in equilibrium when conditions of a reaction are altered.
Synonyms
A chemistry rule saying a balanced reaction changes to oppose a change and reach a new balance
A rule that says a balanced chemical system shifts to undo a change and move back toward balance
When a balanced chemical system faces a change, it shifts to partly undo the change

Morphology
Le + Chatelier-Braun + principle
This is an eponymous scientific name: the constituents are proper names ('Le Chatelier-Braun') plus the generic noun 'principle'. A B1 learner who knows the word 'principle' would only know it denotes a rule, but knowing the names provides no clue to the specific equilibrium-adjustment meaning, so the MWE is not derivable from its parts.
Etymology
Le Chatelier-Braun principle compares a chemical system to a balance: if you push one side by changing temperature, pressure, or concentration, the system shifts the other way to push back and find a new balance. That's why it means the system will 'push back' against a change and 'find a new equilibrium'.
