Concentration and Chemical Equilibrium

Increasing the concentration of a reactant will raise the value of $K_{eq}$.

Although concentration changes can shift a reaction’s position, the equilibrium constant $K_{eq}$ remains unchanged as long as the temperature is constant.

Increasing a reactant’s concentration shifts the equilibrium toward the products to re-establish equilibrium.

Removing a product from the system causes the equilibrium to shift in the direction that produces more product.
