Question

How does concentration effect equilibrium according to Le Chatelier's principle?

Answer 1

The way I see it is that:

If the Concentration of A Increases, the equilibrium will shift to the side with the smallest concentration of A.

If the Concentration of A Decreases, the equilibrium will shift to the side with the highest concentration of A.

Is this correct or?

Answer 2

Almost. If the concentration of A increases, the equilibrium will shift to the side of the reaction which consumes some of the A, (the side where A reacts to form something else) to offset the stress. etc. ...
