Le Chatelier’s Principle

“If a system in equilibrium is subjected to a stress, a change that will offset the stress will

occur in the system.”

Page 2: Le Chatelier’s Principle “If a system in equilibrium is subjected to a stress, a change that will offset the stress will occur in the system.”

Le Chatelier’s Principle

“If a ‘stress’ is applied to a system in equilibrium,

the equilibrium condition is upset; a net reaction occurs in that direction

which tends to relieve the ‘stress,’ and a new equilibrium is obtained.”
