According to Le Chatelier’s Principle, what happens when reactants are added?

Le Chatelier's Principle states that when a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium. When reactants are added to a system at equilibrium, the concentration of the reactants increases.

To counter this increase, the system will shift the equilibrium position toward the product side (right side of the reaction) in order to consume the added reactants. This shift toward the right means that more products will form to restore balance, resulting in a new equilibrium state. Thus, adding reactants leads to a shift to the right because the system seeks to reduce the effect of the change imposed on it.
