Question

A certain reaction occurs in the following steps-

\[\ce{Cl_g + O3(g)->ClO(g) +O2(g)}\]

\[\ce{ClO_g + O(g)->Cl(g) +O2(g)}\]

a) What is the molecularity of each of the elementary steps?

b) Identify the reaction intermediate and write the chemical equation for the overall reaction.

Answer 1

a) 

`Cl_(g) + O_(3(g)) -> ClO_((g)) + O_(2(g))`

Molacularity : Bimolecular

`ClO_((g)) + O_((g)) -> Cl_((g)) + O_(2(g))`

Molacularity : Bimolecular

b) Intermediate: ClO

`Cl_(g) + O_(3(g)) -> ClO_((g)) + O_(2(g))`

`ClO_((g)) + O_((g)) -> Cl_((g)) + O_(2(g))`

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

`O_(3(g)) + O_((g))   ->  2O_(2(g))`                                  Net reaction
