Question: If the concentration of a reactant is increased in a system at equilibrium, what will happen according to Le Chatelier\'s principle?
Options:
Correct Answer: The equilibrium will shift to the right.
Solution:
According to Le Chatelier\'s principle, if a change is made to a system at equilibrium, the system will adjust to counteract that change. Increasing the concentration of a reactant will shift the equilibrium to the right, favoring the formation of products.
