The Elementary Steps for a Catalyzed Reaction Are Shown Below

The elementary steps for a catalyzed reaction are shown below.Identify the catalyst.Identify the reactive intermediate.
H₂O₂(aq) + I−(aq) → H₂O(l) + IO−(aq)
IO−(aq) + H₂O₂(aq) → H₂O(l) + O₂(g) + I−(aq)

A) The catalyst is H₂O(l) ;the reactive intermediate is I−(aq) .
B) The catalyst is IO−(aq) ;the reactive intermediate is I−(aq) .
C) The catalyst is I−(aq) ;the reactive intermediate is H₂O₂(aq) .
D) The catalyst is I−(aq) ;the reactive intermediate is IO−(aq) .
E) The catalyst is H₂O₂(aq) ;the reactive intermediate is I−(aq) .
