A mechanism for the gas phase reaction of fluorine with chlorine dioxide that is

Question

A mechanism for the gas phase reaction of fluorine with chlorine dioxide that is consistent with the observed rate law is: step 1 slow: F3 + ClO, FCIO, +F step 2 fast: F+ CIO, FCIO, (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]"... , where '1' is understood (so don't write it) for m, n etc.) Rate =

Explanation / Answer

step 1 F2 + ClO2 -----------> FClO2 + F slow
step 2 F + ClO2 ------------> FClO2       fast
      -------------------------------------------------
1. F2 + 2ClO2 ------------> 2FClO2 overall reaction
2.F is catalyst
3. F is intermediate
4.rate law
    Rate = K[F2]^1[ClO2]^1
   m = 1 n = 1
