The concentrations of reactants and products are modified.
more reactants will form
If the added substance is a reactant, the equilibrium shifts toward products. If it is a product, it moves towards reactants.
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)
The echilibrium will be restored.
The equilibrium is not maintained.

The equilibrium of the system will be upset.
More Reactants will form!!
Le Chetalier's Principle states "If to a system in equilibrium, a change is applied, the system will react to tend to negate that change" - or the substance of that statement. So if you add product, the system will tend to go to the reverse reaction and produce more reactant. Vice Versa. If more reactant is added, the system reacts to make more product to restore equilibrium.
The equilibrium of the system will be upset.
When a change is imposed on a system at equilibrium, the "position" of the equilibrium shifts in a direction that reduces the effects of that change. For example, if a reactant or product is added, the system shifts AWAY FROM that added component to use the excess up. If heat is added, the system shifts AWAY FROM that added energy energy to use the excess up. If the pressure on a system is increased, the system shifts toward the side with fewer gas molecules.
Le Chatlier's PrincipleIf an equilibrium reaction is occurring and some reactant from either side of the equilibrium is added, the reaction goes in a direction that is to oppose the addition of a reactant. For example. In the equilibrium of CO2 + H2O = H2CO3, if more CO2 is added then the equilibrium shifts in such a way that this change is opposed so more H2CO3 is produced. For more information, research Le Chatlier's Principle.
All concentrations would change.
