The addition of any of the reactants or removal of any of the products favors:
Correct answer: A. forward reaction.
- A. forward reaction.
- B. equilibrium position.
- C. backward reaction.
- D. equilibrium constant.
Explanation
The addition of any of the reactants or removal of any of the products favors the forward reaction.When reactants are added or products are removed, the system is disturbed and shifts in a direction that helps restore equilibrium. According to Le Chatelier's principle, if a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that minimizes the stress.In this case, adding more reactants or removing products creates a stress on the system by increasing the concentration of the reactants or decreasing the concentration of the products. To minimize this stress, the system will shift in the forward direction to consume the excess reactants and produce more products. Therefore, the addition of reactants or removal of products favors the forward reaction.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
