Consecutive elementary reaction
WebReaction products often do not result from single-step reactions of the starting substances but from consecutive elementary reactions via more or less stable intermediate substances (I). Let us consider as the simplest case a series of monomolecular elementary reactions. We will ignore any backward reactions: WebThe reactions in which the reactant forms an intermediate and the intermediate forms the product in one or many subsequent reactions are called consecutive reactions. A →K 1B →K 2C. A= reactant, B= intermediate, C= product. Initially only the reactant A will be present. As the reaction starts, A produces an intermediate B is formed, it ...
