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. I- is a catalyst in this reaction
4. I2 is an intermediate in this reaction
5. This reaction is third order with respect to I-
