What is the molecularity of each of the following elementary

What is the molecularity of each of the following elementary process? Give the rate law for each. A. NO B. CO (g) C. 03 (g) 6) NO2 (g) O2(g) 03 (g) Cl2(g) O2 (g) + (g) + COC12 (g) + O(g) + ecular

Solution

A. NO(g) + O3(g) ----------------> NO2(g) + O2(g)

   Rate = K[NO][O3]

bimolecular . molecularity is 2

B. CO(g) + Cl2(g) -------------------> COCl2(g)

   Rate = K[CO][Cl2]

bimolecular. molecularity is 2

C. O3(g) -------------------> O2(g) + O(g)

    Rate = K[O3]

    unimolecular. molecularity 1
