In chemistry, Le Chatelier's principle, also called Chatelier's principle or "The Equilibrium Law", 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 and sometimes Karl Ferdinand Braun who discovered it independently. It can be summarized as:
- If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established.
This principle has a variety of names, depending upon the discipline using it. See, for example, homeostasis. It is common to take Le Chatelier's principle to be a more general observation, roughly stated:
- Any change in status quo prompts an opposing reaction in the responding system.
In chemistry, the principle is used to manipulate the outcomes of reversible reactions, often to increase the yield of reactions. In pharmacology, the binding of ligands to the receptor may shift the equilibrium according to Le Chatelier's principle, thereby explaining the diverse phenomena of receptor activation and desensitization. In economics, the principle has been generalized to help explain the price equilibrium of efficient economic systems. In simultaneous equilibrium systems, phenomena that are in apparent contradiction to Le Chatelier's principle can occur; these can be resolved by the theory of response reactions.
This was just a short story enjoy the longer version... Students!!!. Le-Chatelier Principle is being explained to you by Mr. Lalit Sardana(IIT-JEE AIR 243).
He is an IIT JEE trainer and the Head of Sardana Tutorials. In this video he is going to teach you effect of concentration, effect of change of temperature, effect of change of volume, effect of change of pressure, effect of addition of inert gases, etc. This video is helpful for the students appearing for 11th CBSE, 12th CBSE, JEE Mains, JEE Advanced, KCET, VITEEE, J and K Engineering exams.
