Le Chatelier’s principle When a system at equilibrium is subjected to a disturbance, its composition adjusts so as to tend to minimize the effect of the disturbance When a system at equilibrium is heated, a) the equilibrium composition of an exothermic reaction will shift towards reactants, b) while the equilibrium composition of an endothermic reaction
According to Le Chatelier’s principle, if a change is made to a system at equilibrium, the system will react to the change to try to restore the equilibrium Wikipedia gives a pretty good definition of Le Chatelier’s principle: When any system at equilibrium is subjected to change in concentration, temperature, volume, or pressure, then the
Le Chatelier's principle, as it is commonly expressed, suggests that a stress applied to a system at equilihrium will lead to a shift in the position of the equilibrium which mini- mizes the effect of that stress It is therefore often armed that On the Misuse of Le Chatelier's Principle for the Prediction of the Temperature
Le Châtelier’s principle states that a system at equilibrium will respond to a stress on the system in such a way so as to relieve the stress and establish a new equilibrium

LeChâtelier’s Principle : A system perturbed from equilibrium shifts its equilibrium position to relieve the applied stress For an increase in temperature, the reaction shifts in the endothermic direction to relieve the stress The decomposition of CO 2, reaction 1, is endothermic in the forward direction Upon an

Le Chatelier Response
Le Chatelier principle is an extension of the Gauss’ principle of least constraints [2,3] into chemical processes Since the time when the principle was initially worded, it is common to say that Le Chatelier ‘s principle is easier to illustrate than to state [4] Well-known examples, used to explain how the principle works, are related to temperature or pressure changes H Le Chatelier

L'équilibre chimique
Le principe de Le Chatelier • toute modification des conditions dans lesquelles une expérience a lieu peut déplacer la position d'équilibre vers la gauche (les réactifs) ou la droite (les produits) • le principe de Le Chatelier dit que si une contrainte (un facteur extérieur) agit sur un système en équilibre, le système

Chatelier principle then establishes the convexity of the value of information in a particular neighborhood of the uncertain variable 5 Second, I discuss additional conditions sufficient to ensure that this positive relation is global These additional conditions are difficult to state exactly; instead, I use a statement in Samuelson (1960) about a global Le Chatelier principle to sketch them

« Principe de Le Chatelier » Le déplacement de l’équilibre se fait de manière à s’opposer à la perturbation qui l’a engendré Attention, ce critère est souvent facile à constater, mais pas toujours Remarque : Un déplacement d’équilibre n’est possible que si le système est au moins divariant (????≥2)
