The dissociation of phosgene gas (COCl_(2)) is represented as : COCl_(2) (g) hArr CO(g) + Cl_(2)(g) When the mixture of these three gases is compressed at constanat temperature , what happens to (i) the amount of CO in the mixture (ii) the partial pressure of COCl_(2) (iii) the equilibrium constant for the reaction ?

Phosgene is:

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)
