Under certain conditions the reaction H2O2 + 3I + 2H*→ I3¯+ 2H2O occurs by the following series of steps: k1 Step 1. H202+H* = H3O2* + k.1 with K (equilibrium constant) = k1/k-1 %3D 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) Use approximations (RDS, eq, steady-state) if necessary The rate constant k for the reaction would be given by
