2 NO (g) + Cl2 (g)
2 NOCl
Which is/are required for a successful reaction between NO and Cl2 molecs?
I. Proper orientation
II. NO/Cl2 Ratio of 2 to 1
III. Sufficient collision energy
I chose I, II, and III since ...
I(if Nitrogen of NO hits the Cl of Cl2, no reaction will occur since O must hit Cl)
II (trimolecular)
III (to surpass Ea)
However, the correct answer excludes II and only chooses I and III ONLY.
I thought II is needed for a successful reaction (mole to mole ratio)
Any help?
