the reaction of hydrogen and iodine monochloride is given as
`H_(2) (g) +2l Cl(g) to 2HCl(g) +I_(2)(g) `
this reaction is of first order with respect to `H_(2) (g) ` and ICI(g) , following mechanisms mechanism A
`H_(2) (g) +2l Cl(g) to 2HCl(g) +I_(2)(g) `
Mechanism B
`H_(2)(g) +ICI(g) to HCI(g) +HI(g) ,` slow
`HI (g) + ICI (g) to HCI(g) +I_(2)(g) .` fast
which of the above mechanism (S) can be consistent with the given information about the reaction ?

Options

A. A only
B. B only
C. Both (1) and (2)
D. Neither (1) nor (2)

Answer
