Which of the following is likely to occur if more reactants are added to a reaction that is at chemical equilibrium?

there will be no effect; the reaction will stay at equilibrium

the reaction will shift to the right (toward the products)

the reaction will shift to the left (toward the reactants)

The reaction will shift to the right (toward the products)

Explanation;Le Chatelier's principle states that changing a factor such as concentration, temperature, or pressure of a reaction at equilibrium will cause the reaction to shift in the direction that counteracts the effect of that change.Therefore, when more reactants are added to a reaction at equilibrium shift  the reaction shifts to the right to make more products.
