Solution: The decomposition of hydrogen peroxide in the presence of iodide ion is believed to occur via this mechanism.  H2O2(aq) + I - (aq) → H2O(l) + IO - (aq)  H2O2(aq) + IO - (aq) → H2O(l) + O2(g) + I - (aq) In this mechanism, I - (aq) is (A) a catalyst. (B) a reactant in the overall reaction. (C) the activated complex. (D) a product of the overall reaction.

Problem

The decomposition of hydrogen peroxide in the presence of iodide ion is believed to occur via this mechanism. 

H2O2(aq) + I (aq) → H2O(l) + IO (aq

H2O2(aq) + IO (aq) → H2O(l) + O2(g) + I (aq)

In this mechanism, I - (aq) is

(A) a catalyst.

(B) a reactant in the overall reaction.

(C) the activated complex.

(D) a product of the overall reaction.
