Le Chȃtelier’s principle can be used to predict the effect that a stress like changing concentration has on a reaction system at equilibrium. If the concentration of a reaction species is increased (at constant T and V), the equilibrium system will shift in the direction that reduces the concentration of that species. If the concentration of a reaction species is decreased, the reverse effect will be observed. View more lessons or practice this subject at https://www.khanacademy.org/science/a...
