In alkaline medium ClO2 oxidizes H2O2  to O2 and reduced itself to  Cl- then how many mole of H2O2 will oxidize by one mole of ClO2

H2O2  → O2H2O2 + 2OH- → O2 + 2H2O + 2e---(1)H2O2 + 2OH- → O2 + 2H2O + 2e- ×5ClO2 → Cl-ClO2 + 2H2O + 5e-  → Cl- + 4OH---(2)ClO2 + 2H2O + 5e-  → Cl- + 4OH- ×2(1)x5 + (2)x2 ⇒2ClO2 + 5H2O2 + 2 OH-  → 2Cl- + 5O2 +6H2O2ClO2 ≡ 5H2O2∴   ClO2 ≡ 2.5  H2O2
