Consider the proposed mechanism for the decomposition reaction 2 h₂o₂(aq) → 2 h₂o(l) o₂(g) in the presence of i⁻(aq). What is the rate law for this reaction?.

Answer:

C) rate = k[H₂O₂][I⁻]

Step-by-step explanation:

Step One (Slow) is biomolecular and has a rate law - rate = k₁[H₂O₂][I⁻]. Step one is the slow step in the proposed mechanism, whereas step two is the fast step. If a fast step follows a slow step, it does not impact the overall rate law. Henceforth, the final rate law = k[H₂O₂][I⁻].
