Question

The thermal decomposition of nitryl chloride is proposed to occur by the following mechanism:

(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) for m, n etc.)

Rate =

Explanation / Answer

tep 1 slow:   NO2Cl --------> NO2 + Cl

step 2 fast:   Cl + NO2Cl -------> NO2 + Cl2

          ------------------------------------------------------

             2NO2Cl ---------------> 2NO2 + Cl2 over all reaction

2 catalyst is NO2

3. cl is intermediate

4. Rate law

rate = K[NO2Cl]
