The following reaction exhibits the rate law: Rate = k[NO2]^2[Cl2].
(a) Explain why the following mechanism is not plausible for this reaction.
Fast: NO + Cl2<-->NOCl + Cl
Slow: NO + Cl---->NOCl
(b) Propose a two-step mechanism involving one fast reversible step and one slow step that is consistent with the net equation and the observed rate law.
