$2K\,Cl{O_3}\xrightarrow{{}}2KCl + 3{O_2}$ law of mass action
$H_{2(g)} + 2ICl_{(g)} \rightarrow 2HCl_{(g)} + I_{2(g)}$
This reaction is of first order with respect to $H_{2(g)}$ and $ICl_{(g)},$
following mechanisms were proposed.
Mechanism $A\, :$
$H_{2(g)} + 2ICl_{(g)} \rightarrow 2HCl_{(g)} + I_{2(g)}$
Mechanism $B\, :$
$H_{2(g)} + ICl_{(g)} \rightarrow HCl_{(g)} + HI_{(g)}\, ;$ slow
$HI_{(g)} + ICl_{(g)} \rightarrow HCl_{(g)} + I_{2(g)} \,;$ fast
Which of the above mechanism(s) can beconsistent with the given information about the reaction ?
