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: h2o2 + 3 i- + 2 h+ ? i3- + 2 h2o
step 1. h2o2 + h+ ? h3o2+
step 2. h3o2+ + i- ? h2o + hoi
step 3. hoi + i- ? oh- + i2
step 4. oh- + h+ ? h2o
step 5. i2 + i- ? i3-
how many of the following statements are correct based on the information given?
1. i3- is a product of this reaction
2. i2 is a reactant in this reaction
3. h+ is a catalyst in this reaction
4. i2 is an intermediate in this reaction
5. this reaction is second order with respect to h+
answer options: 3, 5, 1, 0, 2
