Question

The reaction 2 NO(g) + O2(g) --> 2 NO2(g) proceeds through the following mechanism:

     2 NO(g) --> N2O2(g)
N2O2(g) + O2(g) --> 2 NO2(g)




(a) The second step of this mechanism is rate-determining (slow). What is the rate law for this reaction?


Rate = k [NO] [O2]
Rate = k [NO]2 [O2]    
Rate = k [NO] [O2]2
Rate = k [NO]1/2 [O2]
Rate = k [NO] [O2]1/2
Rate = k [NO]2
Rate = k [NO]2 [O2]1/2

 

(b) What would the rate law be if the first step of this mechanism were rate-determining?

Rate = k [NO] [O2]
Rate = k [NO]2 [O2]    
Rate = k [NO] [O2]2
Rate = k [NO]1/2 [O2]
Rate = k [NO] [O2]1/2
Rate = k [NO]2
Rate = k [NO]2 [O2]1/2
Rate = k [NO]
