What is the expected outcome of increasing the concentration of reactants in an equilibrium system?

• A. It leads to more formation of reactants
• B. It results in more formation of products
• C. It creates an imbalance
• D. It causes no change

Answer: (B)

Increasing the concentration of reactants in an equilibrium system shifts the equilibrium position according to Le Chatelier's principle. This principle states that if a system at equilibrium is disturbed by changing the conditions (such as concentration, temperature, or pressure), the system will respond by partially counteracting that change to establish a new equilibrium. When the concentration of the reactants is increased, the system will respond by favoring the forward reaction, which produces more products. This is because the system seeks to minimize the disturbance caused by the increased concentration of reactants by converting them into products until a new equilibrium is established. Thus, the expected outcome is an increase in the formation of products.
