Question

The decomposition of hydrogen peroxide is catalyzed by iodide ion. The catalyzed reaction is thought to proceed by a two-step mechanism:
H2O2(aq)+I?(aq)?H2O(l)+IO?(aq)(slow)IO?(aq)+H2O2(aq)?H2O(l)+O2(g)+I?(aq)(fast) Part A Write the chemical equation for the overall process.          Express your answer as a chemical equation. Identify all of the phases in your answer.
Part B Identify the intermediate, if any, in the mechanism.          Express your answers as a chemical expression. If there is more than one answer, separate them by a comma.
Part C Assuming that the first step of the mechanism is rate determining, predict the rate law for the overall process.          Use a for [H2O2], b for [I?], c for [IO?], d for [H2O] and k for the rate constant.
