A system at equilibrium has two aqueous products and two aqueous reactants. An additional amount of one of the products is added to the system. After the addition, which of the following will change?Select the correct answer below:a. the amount of the added productb. the amount of the other productc. the amounts of the reactantsd. all of the above

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given reaction:

[tex]A(aq)+B(aq)\rightleftharpoons C(aq)+D(aq)[/tex]

If the concentration of one of the products is increased, so according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease of concentration of product takes place. Therefore, the equilibrium will shift in the left direction i.e. towards the reactants and thus more reactants will be formed.
