The idea that when a system at equilibrium is stressed, it will react to relieve that stress and return to equilibrium is known as:

• Boyle's Law
• Le Chatelier's Principle
• Charles Law
• Denninger's Law

Le Chaltelier's Principle states that if a chemical system at equilibrium is stressed,

• the system will adjust to increase the stress
• the system will adjust to reduce the stress
• the system will not adjust
