QuestionAnswer
Henri Louis Le Châtelier was a French-Italian chemist who worked in the late nineteenth and early twentieth centuries. His most famous work involves [...] reactions. Henri Louis Le Châtelier was a French-Italian chemist who worked in the late nineteenth and early twentieth centuries. His most famous work involves equilibrium reactions.
Le Châtelier's principle states that any change to a chemical system at equilibrium causes the reaction to move in the direction that will [...], the effect of that change. Le Châtelier's principle states that any change to a chemical system at equilibrium causes the reaction to move in the direction that will minimize, or offset, the effect of that change.
Chemists talk about the equilibrium shifting. If more products are formed, the equilibrium has shifted toward the product side. Because this is on the [...] side of the equation, you say equilibrium shifts to the [...]. Chemists talk about the equilibrium shifting. If more products are formed, the equilibrium has shifted toward the product side. Because this is on the right side of the equation, you say equilibrium shifts to the right.
If you add reactants, equilibrium shifts to the [...] If you add reactants, equilibrium shifts to the right
If you remove reactants, equilibrium shifts to the [...] If you remove reactants, equilibrium shifts to the left
If you add products, equilibrium shifts to the [...] If you add products, equilibrium shifts to the left
If you remove products, equilibrium shifts to the [...] If you remove products, equilibrium shifts to the right
Reactions involving [...] are particularly sensitive to changes in pressure. Reactions involving gases are particularly sensitive to changes in pressure.
Increasing pressure shifts equilibrium to the side with less [...]. Increasing pressure shifts equilibrium to the side with less gas.
