How does Le Chatelier's Principle describe an equilibrium response to a stress?

Answer 1

...well the equilibrium moves in such a direction as to RELIEVE the external stress....

...and as I seem to remind my students ALL THE TIME #"RELIEVE "!=" COUNTERACT"#...and so suppose we gots the equilibrium...

#ArightleftharpoonsB#

...if the system has reached equilibrium...and we REMOVE, somehow, product #B#...the equilibrium moves to the right...in response to the new post-equilibrium conditions in order to resatisfy the equilibrium constant. And thus a change in reaction conditions...removal of #B# can drive the equilibrium to the right and the reaction to completion.

Le Chatelier's Principle states that if a system at equilibrium is subjected to a stress, the system will adjust to counteract the effect of the stress and restore equilibrium.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
