Problem
The disproportionation of hydrogen peroxide in aqueous solution is represented overall by
2 H₂O₂(aq) → 2 H₂O(l) + O₂(g)
Iodide ion, I⁻(aq), is known to catalyze this reaction. Propose a mechanism that satisfies all of the following conditions:
• only bimolecular elementary steps
• I⁻ is regenerated by the final step (acts as a catalyst)
• no more than three elementary steps
List the elementary steps and clearly identify any reaction intermediate(s).
