Le Chatelier's Principle in Industry

Definition

Le Chatelier's Principle states that if an external change is applied to a system at equilibrium, the system will adjust to counteract that change and restore a new equilibrium. In industry, this principle is crucial for optimizing chemical reactions, ensuring maximum product yield, and enhancing reaction efficiency by manipulating conditions such as concentration, temperature, and pressure.
