For the preparation of nitrosyl chloride from NO and Cl2 a mechanism involving steps has been proposed.

Step I : NO(g) + Cl2 (s) → NOCl2(g)

Step II : 2NOCl (g) + NO(g) → 2NOCl(g)

Rate law for the reaction is Rate = k[NO][Cl2]

The rate limiting step for this reaction is :–

(a) Step I 

(b) Step II

(c) Both (a) & (b) 

(d) either of the spets I or II
