Question

What is Le Chatelier's principle?

Answer 1

We need to understand what Le Chatelier's principle is and accordingly summarize it. Le Chatelier's principle, commonly known as Chatelier's law (or the Equilibrium Law), is a chemistry principle that predicts the effect of a change in circumstances on chemical equilibria. The concept is named after French scientist Henry Louis Le Chatelier, however Karl Ferdinand Braun is frequently credited with discovering it independently.

Complete answer:
We need to know that if a dynamic equilibrium is upset by altering the circumstances, the location of equilibrium moves to compensate for the change and restore an equilibrium, according to Le Chatelier's principle. When a chemical reaction is at equilibrium and a change in pressure, temperature, or product or reactant concentration occurs, the equilibrium changes in the opposite direction to compensate for the change. We need to know that when equilibrium-affecting parameters such as concentration, pressure, temperature, and inert gases are modified, the equilibrium will move in the direction where the effects of these changes are neutralised.

Note:
We must note that the concept of Le Chatelier can be used to forecast how a system would behave in response to changes in pressure, temperature, or concentration. As we know that according to Le Chatelier's principle, adding heat to a reaction favours the endothermic direction since it minimises the quantity of heat produced in the system. The reaction will move to the right as the concentration of reactants rises, whereas the reaction will move to the left as the concentration of products rises.
