What does Le Chatelier's principle state?

Answer 1

#"...when a system at equilibrium is subject to an external stress,"# #"the equilibrium will move so as to oppose the stress....."#

It is important to realize that #"oppose"# does not equal #"counteract"#. Under the new conditions, a new equilibrium may develope. We speak of the initial response of a system whose equilibrium is perturbed.

Le Chatelier's principle states that if a system at equilibrium is subjected to a change in concentration, temperature, pressure, or volume, the equilibrium will shift to counteract the imposed change and establish a new equilibrium.
