The reaction of hydrogen and iodine monochloride is given as H_(2 (g)

1.	The reaction of hydrogen and iodine monochloride is given as H_(2 (g)) + 2I Cl_((g)) + I_(2 (g)) This reaction is of first order with respect to H_(2 (g)) and I Cl_((g)) following mechanisms were proposed Mechanism A : H_(2(g)) + 2I Cl_((g)) to HCl_((g)) + I_(2(g)) Mechanism B : {:(H_(2 (g)) + ICl_((g)) to HCl_((g)) + HI_((g)) "Slow") , (HI_((g)) + ICl_((g)) to HCl_((g)) + I_(2(g)) "Fast"):} Which of the above mechanism(s) can be consists with the given information about the reaction
Answer» B only A and B only NEITHER A nor B A only Solution :Rate of reaction determined by rate determining step or slowest step . Because the mechanism B involves ONE molecule of I CL in slowest step so mechanism B is APPROXIMATE .
