However, the second law requires only that the amounts of reactants and final products change monotonically, the amounts of intermediate species, present in much Tower concentrations than those of reactants, may indeed oscillate if the governing dynamic law contains suitable feedback loops. By 1968 Ilya Prigogine and coworkers had used a hypothetical chemical mode!
