10. A multi-step reaction involving hydrogen peroxide and iodine anion is thought to have the following steps:
Step 1: H2O2 + I^- → H2OH + IO^-
Step 2: H2O2 + IO^- → H2O + O2 + I^-
Write out the rate law for each fundamental step and determine the molecularity for each step. Identify the catalyst and intermediate of reaction.
