Under certain conditions the reaction H2O2 + 3I– + 2H+→ I3– + 2H2O occurs by the following series of steps:
 
k1
 
Step 1.
 
H2O2 + H+H3O2+
 
k–1
 
Step 2.
 
H3O2+ + I–→ H2O + HOI
(slow, rate constant k2)
 
Step 3.
 
HOI + I–→ OH– + I2
(fast, rate constant k3)
 
Step 4.
 
OH– + H+→ H2O
(fast, rate constant k4)
 
 
Step 5.
 
I2 + I–→ I3–
(fast, rate constant k5)

​

The rate constant k for the reaction would be given by:

 
Reference: Ref 12-17

​

​


◦ k = k2
◦ k = k2k3
◦ k = k2K
◦ k = k5
◦ k = Kk2k3k4k5
