Question
A proposal mechanism for the gas phase reaction between nitrogen monoxide and oxygen is as follows step 1 fast. NO + O_2 NO_3 sleep 2 slow: NO_3 + NO rightarrow 2 NO_2 What is the equation for the overall reaction ' Use the smallest integer coefficients possible. If a box is not needed, leave it blank Enter the formula of any specie# that acts as a reaction intermediate? If none leave box blank: 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 understand (so don't write it if It's a '1') for m, n etc Rate =Explanation / Answer
step-1 NO + O2 -------> NO3
Step -2 NO3 + NO -------> 2NO2
---------------------------------------------------------
2NO +O2 ---------> 2NO2 over all reaction
Reaction intermediate is NO3
Rate law
Rate = K[NO]2[O2]1
