Increasing the concentration of reactants in a chemical equilibrium influences the balance of the reaction according to Le Chatelier's principle. This principle states that if a system at equilibrium is disturbed, it will adjust to minimize the disturbance and restore equilibrium.

When the concentration of reactants is increased, the system responds by favoring the forward reaction. This means that more products will be produced in order to counteract the added concentration of reactants. As a result, the position of the equilibrium shifts to the right, favoring the formation of products.

This shift occurs as the system seeks to reduce the increased concentration of reactants by converting some of them into products until a new equilibrium state is established. This principle is fundamental in understanding how reactant and product concentrations influence the dynamics of equilibrium reactions in organic chemistry and is widely applicable in various chemical contexts.
