Pleaaaase help, im stumped on this problem:

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


Step I   NO2 + F2 Rightwards Arrow NO2F + F   (slow)


Step II   F + NO2 Rightwards Arrow NO2F   (fast)


Which of the following statements are true?



a)   The slowest step is the rate determining step


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


c)   The overall reaction is F + F2 Rightwards Arrow F3


d)   The experimental rate law is k[NO2][F2]



there can be more than one right answer.

a) and d) thats for sure
the law satisfies the slow reaction and yea it is the rate determining reaction

although if the overall reaction was known this question could have been alot more easier.
