Chemical Equilibrium and Le Châtelier's Principle

Easy General Chemistry Chemical Equilibrium

The equilibrium of a chemical reaction is characterized by the constancy of the concentration of reactants and products over time. Consider the following reaction at equilibrium:

A + B <=> C + D

If the concentration of reactant A is decreased, which of the following statements is true regarding the shift in equilibrium according to Le Châtelier's principle?

The equilibrium will shift to the right, favoring the formation of products C and D.

The equilibrium will shift to the left, favoring the formation of reactants A and B.

The equilibrium will remain the same, as concentrations no longer change.

The reaction will proceed irreversibly toward products C and D.
