A suggested mechanism for the reaction of nitrogen dioxide and fluorine is?

Question

A suggested mechanism for the reaction of nitrogen dioxide and fluorine is


Step I NO2 + F2 --> NO2F + F (slow)


Step II F + NO2 --> NO2F (fast)


Which of the following statements are true?


a) Step II is the rate determining step


b) For the rate determining step : rate = k[NO2][F2]


c) The overall reaction is 2NO2 + F2 --> 2NO2F


d) The experimental rate law is k[NO2]

Can be more than 1 correct answer

Answer 1

the correct answer is bc

Answer 2

b is the only answer
he went over this in lecture 7

a) is wrong because step 1 is the rate determining step because the slow step is always the rate determining step
c) is wring because the over all reaction is what you have after canceling out every thing so you end up with F2--->2F
d) is wrong because the rate law is K[NO2][F2]
(this is explained in the work book on pg 161)
