Question

Given below is a possible three-step mechanism describing the reaction of hydrogen peroxide with iodide ion in an acidic solution.

Step 1: (slow) H₂O_2(aq) + I^-_(aq) ---> OH^-_(aq) + HOI_(aq)

Step 2: (very fast) OH^-_(aq) + H⁺_(aq) ---> H₂O_(liq)

Step 3: (fast) HOI_(aq) + H⁺_(aq) + I^-_(aq) ---> I_2(aq) + H₂O_(liq)

Assuming that the above reaction mechanism is correct, write the expected rate law expression. Is your experimental data consistent with the proposed mechanism? Explain your answer.
