The reaction of hydrogen and iodine monochloride is given as:H2 (g) + 2ICl (g) → 2 HCl (g) + I2 (g)This reaction is of first order with respect to H2 (g) and ICI (g), following mechanisms were proposed:Mechanism A:H2 (g) + 2 ICl (g) → 2 HCl (g) + I2 (g) Mechanism B:H2 (g) + ICl (g) →HCl (g) + HI (g) ;slowHI (g) + ICl (g) → HCl (g) + I2 (g); fastWhich of the above mechanism (s) can be consistent with the given information about the reaction?
