The rate law for the reaction (2H₂ + 2NO → N₂ + 2H₂0) between hydrogen gas (H2) and nitric oxide (NO) is experimentally determined to be rate = k[H₂] [NO]₂. Which mechanism below could be a valid mechanism for this reaction?
a. H₂+NO→H₂NO(fast)
H₂NO+H₂→N₂+2H₂O (slow)
b. H₂​+NO→N₂+2H₂​O (fast)
H₂+NO→H₂​NO (slow)
c. H₂​+NO→H₂​NO (slow)
H₂NO+H₂​→N₂​+2H₂​O (fast)
d. 2H​+2NO→N₂​+2H₂​O (elementary)
