Henri Le Chatelier

Henri Le Châtelier was a French chemist known for formulating what is now called Le Châtelier’s Principle. This principle states that if a chemical system at equilibrium experiences a change in conditions—such as pressure, temperature, or concentration—the system will adjust itself to counteract that change and restore balance. Imagine adding more reactant to a reaction; the system responds by producing more product until a new balance is reached. This concept helps chemists predict how reactions will shift under different conditions, aiding in the design and control of chemical processes.
