ANSWER:Solution 63P
Here we have to explain the proposed mechanism is valid or not.
Step 1
In a study of nitrosyl halides, a chemist proposes the following mechanism for the synthesis of nitrosyl bromide:
NO (g) + Br2 (g) ⇄ NOBr2 (g) [fast]
NOBr2 (g) + NO (g) → 2NOBr (g) [slow]
In this question it has been given that the rate law is, rate = k[NO]2[Br2]
1st we will write the overall reaction by adding the two given reactions as follows,
NO (g) + Br2 (g) ⇄ NOBr2 (g) [fast]
NOBr2 (g) + NO (g) → 2NOBr (g) [slow]
Overall reaction : 2NO (g) + Br2
