Question

what happens if more product is added to a system at equilibrium?
a. more reactants will form.
b. more products will form.
c. concentrations will not change.
d. only the concentration of that product will increase.

Explanation:

According to Le - Chatelier's principle, when a system at equilibrium is disturbed, it will shift to counteract the change. Adding more product increases the product concentration. The system will shift in the reverse direction to consume the added product, thus forming more reactants.

Answer:

A. More reactants will form.
