Henry Louis Le Chatelier

Henry Louis Le Châtelier was a French chemist who formulated a principle explaining how chemical reactions respond to changes. His principle states that if a system at equilibrium (where forward and reverse reactions balance) experiences a disturbance—such as changes in concentration, temperature, or pressure—the system will adjust to counteract the change and restore balance. This behavior helps predict how reactions shift under different conditions, which is fundamental in industrial chemistry and laboratory processes. Le Châtelier's principle thus provides a fundamental understanding of reaction dynamics and how to control chemical processes effectively.
