Which represents the overall (net) reaction of this mechanism: step 1: H2O2 + I- → H2O + OI- step 2: H2O2 + OI- → H2O + O2 + I-
11111nata11111 [884]

Answer:

A. 2H₂O₂  → 2H₂O + O₂

Explanation:

  • 1. H₂O₂ + I⁻ → H₂O + OI⁻
  • 2. H₂O₂ + OI⁻ → H₂O + O₂ + I⁻

If we <u>make a net sum of both reactions</u>, we're left with:

  • H₂O₂ + I⁻ + H₂O₂ + OI⁻ → H₂O + OI⁻ + H₂O + O₂ + I⁻

Grouping species:

  • 2H₂O₂ + OI⁻ + I⁻ → 2H₂O + OI⁻ + O₂ + I⁻

There is OI⁻ at both sides, so it is eliminated -same goes for the catalyst, I⁻-.

  • 2H₂O₂  → 2H₂O + O₂

Thus the answer is option A.
