A Proposed Mechanism for the Reduction of Nitrogen as NO $\to$

A proposed mechanism for the reduction of nitrogen as NO by hydrogen is: Step 1: H₂(g) + 2 NO(g) $\to$ N₂O(g) + H₂O(g) (slow)
Step 2: N₂O(g) + H₂(g) $\to$ N₂(g) + H₂O(g) (fast)
Which of the following statements is NOT true?

A) The energy profile for this reaction probably has two maxima.
B) The reaction rate is probably second order in NO.
C) The reaction rate is probably first order in H₂.
D) N₂O is an intermediate.
E) The activation energy for step 2 is probably less than that of step 1.
