Which of the following is an elementary step?
A.NO₃ + CO → NO₂ + CO₂
B.N₂ + 3H₂ → 2NH₃
C.C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
D.2KClO₃ → 2KCl + 3O₂
Explanation
Core Concept
This is a single collision event between two species — an elementary bimolecular step. Its rate law would be k[NO₃][CO].
Correct Answer
ANO₃ + CO → NO₂ + CO₂
