Le Chatelier-braun Principle (Noun)
Meaning
The principle that if any change is imposed on a system that is in equilibrium then the system tends to adjust to a new equilibrium counteracting the change.
Classification
Nouns denoting cognitive processes and contents.
Examples
- The Le Chatelier-Braun principle explains why an increase in the concentration of reactants in an equilibrium reaction often results in an increase in the products.
- If the concentration of hydrogen is increased in the equilibrium reaction between hydrogen and nitrogen to form ammonia, the Le Chatelier-Braun principle states that the equilibrium will shift in favor of ammonia.
- According to the Le Chatelier-Braun principle, when the pressure in an equilibrium system is decreased, the equilibrium will shift to counteract the change, resulting in more gas and less liquid.
- The Le Chatelier-Braun principle states that an increase in temperature in an exothermic equilibrium reaction will cause a shift in the equilibrium to the left, favoring the reactants.
- By understanding the Le Chatelier-Braun principle, chemists can predict how changes in concentration, pressure, or temperature will affect the equilibrium constant in a reversible reaction.
