Can someone please help me? I really don't understand this...
The reaction: 2 NO + Cl2 -- 2 NOCl has the rate
law: rate of reaction = k[NO]^2 [Cl2]. Propose a two step mechanism for this reaction consisting of a fast reversible first step, followed by a slow step.

2 NO $\rightarrow$ N$_2$O$_2$ 
N$_2$O$_2$ + Cl$_2$ $\rightarrow$ 2 NOCl
