Question

In class we watched a demonstration where the color of the solution oscillated between orange and blue. This is a very complicated reaction with multiple pathways the reaction can take. One pathway can be described as follows: H_2O_2 + 3 I^- + 2 H^+ rightarrow I_3^- + 2 H_2O Step 1. H_2O_2 + H^+ rightarrow H_3 O_2^+ Step 2. H_3O_2^+ + I^- rightarrow H_2O + HOI Step 3. HOI + I^- rightarrow OH^- + I_2 Step 4. OH^- + H^+ rightarrow H_2O Step 5. I_2 + I^- rightarrow I_3^- How many of the following statements are correct based on the information given? Select all that are Correct. There are no catalysts in this reaction There are three different intermediates in this reaction The reaction is first order with respect to H_2O_2 If step 1 were the rate determining step the order of the overall reaction would be second order
