Le Chatelier's principle predicts that when a stress is applied to an equilibrium mixture, the equilibrium will shift to relieve the stress. Stresses include temperature changes, pressure changes, and changes in the concentrations of species in the mixture. For example, increasing the concentration of a reactant drives the reaction forward; increasing the concentration of a product drives it backward.
a system that in equilibrium is disturbed adjusts so as to minimize the disturbance.
The idea that a system at equilibrium will respond to a stress placed upon it in such a manner as to partially offset that stress. The principle was first stated in 1888 by French physical chemist Henri Le Chatelier (1850-1936).
if a change is imposed on a system at equilibrium, the position of the equilibrium will shift in a direction that tends to reduce the effect of that change
system at equilibrium, when subjected to a disturbance, responds in a way that tends to minimize the effect of the disturbance."
the principle that if any change is imposed on a system that is in equilibrium then the system tends to adjust to a new equilibrium counteracting the change
this principle states that if a system is placed under stress, it will act so as to relieve the stress. Applied to chemical reactions, it means that if product or byproduct is removed from the system, the equilibrium will be upset, and the reaction will produce more product to make up for the loss. In polymerizations, this trick is used to make polymerization reactions reach high conversion.
If a system in equilibrium is subjected to a stress, then the system will alter so as to oppose the effect of the stress.
States that a system at equilibrium, or striving to attain equilibrium, responds in such a way as to counteract any stress placed upon it. If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.
In chemistry, Le Chatelier's principle can be used to predict the effect of a change in conditions on a chemical equilibrium. The principle is named after Henry Louis Le Chatelier.
