22. The use of N₂O₅ as a nitrifying agent is a new type of green nitrification technology, which has been widely used in industries such as energy-containing materials and pharmaceuticals. For the reaction 2N₂O₅(g) → 4NO₂(g) + O₂(g) ， the following reaction sequence was proposed,
where it can be approximated that the second step does not affect the equilibrium of the first step. Which of the following statements is correct?
(A) the rate of the reverse reaction of the first step<the rate of the reaction of the second step
(B) The only intermediate product of the reaction is NO₃.
(C) The collision of NO₂with NO₃ in the second step is only partially effective.
(D) The activation energy of the reaction in the third step is higher than the other two.
(E) The rate law of this reaction is rate = k[NO₂][NO₃].
