Solution: The following reaction has the following rate law: Rate = k[Br2][NO]2 .  2 Br2 (g) + 2 NO (g) → N2 (g) + 2 Br2O (g) The proposed mechanism for the reaction is : Br2 (g) + NO (g) → N (g) + Br 2O (g)

Problem

The following reaction has the following rate law: Rate = k[Br2][NO]2 . 

2 Br2 (g) + 2 NO (g) → N2 (g) + 2 Br2O (g)

The proposed mechanism for the reaction is :

Br2 (g) + NO (g) → N (g) + Br 2O (g) [SLOW]

N (g) + NO (g) → N2 (g + O (g) [FAST]

O (g) + Br2 (g) → Br2O (g) [FAST]

Which of the following statements is/are  false?

a) The rate determining step is bimolecular.

b) There are three elementary steps in the reaction mechanism.

c) The mechanism possesses a catalyst.

d) O is the only reaction intermediate in this reaction mechanism.

e) This not a valid mechanism for the reaction.
