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_2 O_2 + 3I^- + 2H^+ rightarrow I_3^- + 2 H_2 O Step 1. H_2 O_2 + H^+ rightarrow H_3 O_2^+ Step 2. H_3 O_2 + I^- rightarrow H_2 O + HOI Step 3. HOI + I^- rightarrow OH^- + I_2 Step 4. OH^- + H^+ rightarrow H_2 O Step 5. I_2 + I^- rightarrow I_3^- How many of the following statements are correct based on the information given? H+ is a catalyst in this reaction HOI is an intermediate in this reaction This reaction is third order with respect to I^- I_3^- is a product of this reaction I_2 is a reaction in this reaction 3 1 2 5 0
