Question

A proposed mechanism for the gas phase reaction between nitrogen monoxide and oxygen is as follows:

..... step 1 ..... fast: ...... NO + O2  ----> <----- NO3

..... step 2 ..... slow: .... NO3 + NO -------> 2 NO2

(1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank.

__________ + _________ -------> ___________ + ______________

(2)   Which species acts as a catalyst? Enter formula. If none, leave box blank:  ________________  

 

(3)   Which species acts as a reaction intermediate? Enter formula. If none, leave box blank:  _____________  

(4) Complete the rate law for the overall reaction that is consistent with this mechanism.
Use the form k[A]m[B]n , where '1' is understood (so don't write it if it's a '1') for m, n etc.

Rate =   _____________
