The reaction of formation of phosgene fr...

The reaction of formation of phosgene from `CO and Cl_(2)" is "CO + Cl_(2) rarr COCl_(2)` The proposed mechanism is
(i) `Cl_(2) ? K-1 2Cl` (fast equilibrium)
(ii) `Cl+CO ? K-2 COCl` (fast equilibrium)
(iii) `COCl+Cl_(2) overset (k_(3)) rarr COCl_(2)+Cl` (slow) Show that the above mechanism leads to the following rate law `(d[COCl_(2)])/(dt) =K [CO][Cl_(2)]^(3//2)`
Where `K=k_(3) ""(k_(2))/(k-2) ((k_(1))/(k-1))^(1//2)`
