Solution: Given the following proposed mechanism, predict the rate law for the overall reaction.2NO2 + Cl2 → 2NO2 Cl (overall reaction) MechanismNO2 + Cl2 → NO2 Cl + Cl              slowNO2 + Cl → NO2 Cl      

Problem

Given the following proposed mechanism, predict the rate law for the overall reaction.

2NO2 + Cl2 → 2NOCl (overall reaction) Mechanism

NO2 + Cl2 → NO2 Cl + Cl              slow

NO2 + Cl → NO2 Cl                       fast

A) Rate = k[NO 2 ][Cl]

B) Rate = k[NO 2 ][Cl 2 ]

C) Rate = k[NO 2 Cl] 2

D) Rate = k[NO 2 Cl][Cl] 2

E) Rate = k[NO 2 ]2 [Cl2 ] 2
