1.	The reaction of hydrogen and iodine monochloride is given as : The reaction is of first order w.r.t to hydrogen and iodine monochloride, following mechanisms are proposed. Mechanism A : Mechanism b : Which of the above mechanism(s) are consistent with the given Information about the reaction?
Answer» Correct option is B II only According to question the given reaction is first order in H 2 (G) and also first order in ICl(g) so, the slowest (rate determining) step in the reaction should involve H 2 (g) & ICl(g) one mole each. The mechanism II is seeming consistent with the conditions stated as:- H 2 (g)+ICl(g)⟶HCl(g)+HI(g) (SLOW) Rate=K[H 2 ][ICl] & HI(g)+ICl(g)⟶HCl(g)+I 2 (g) (fast)
