A reaction has a characteristic point where it will no longer produce more of the desired product. When a reaction is at equilibrium the rate of the forward reaction equals the rate of the reverse reaction, so reactants and products are produced (and consumed) at the same rate. The position of the equilibrium depends on the reaction. In some cases the production of the reaction products is highly favorable and the equilibrium concentration of the reactants is negligible. In other cases (such as the dissociation of weak acids) the equilibrium lies closer to the reactant side, so there are actually more reactant molecules than product molecules in a given sample at equilibrium.
