The rate law for the reaction H₂O₂ + 2H⁺ + 2I^-→ I₂ + 2H₂O is rate = k[H₂O₂][I^-]. The following mechanism has been suggested. H₂O₂ + I^-→ HOI + OH^-(slow)
OH^-+ H⁺→ H₂O (fast)
HOI + H⁺ + I^-→ I₂ + H₂O (fast)
Identify all intermediates included in this mechanism.

Question

Quizplus · Accepted Answer

The intermediates in this mechanism are HOI and OH^-, which are both included in reaction step (1) and participate in subsequent steps of the mechanism. The other species (H⁺, I^-, and H₂O) are either reactants or products in the given mechanism.
