Part c.ii Sample Response: Yes. Step 2 is slow; therefore, it is the rate-determining step of this mechanism. The rate law of this elementary reaction is rate = k [N₂O₄]. Because N₂O₄ is an intermediate, it cannot appear in the rate law of the overall reaction. Because Keq = [N₂O₄]/ [NO₂]² in step 1, [N₂O₄] = Keq [NO₂]².FRQ Types on the AP Chemistry Exam.
