Write a written response for 40 points + ! explain the impact that changing concentrations has on a system in a state of dynamic equilibrium. what will happen when reactants are added to a reversible reaction mixture at equilibrium?

adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products.

reversible reactions are usually self-correcting. If they are thrown off balance by a change in concentration, temperature, or pressure, the system will naturally shift to re-balance itself.

hope this helps

According to Le Chetelier’s Principle, in a dynamic equilibrium when a stress is applied to the system, the equilibrium shifts in such a direction to minimize the stress.

When reactants are added to a reversible reaction mixture at equilibrium, the reactants will get consumed and more of it will get converted to products. Thus the equilibrium will shift to the product side or the right side of the equilibrium.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
