question 45

Multiple Choice

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.

• A) H⁺and I^-
• B) H⁺ and HOI
• C) HOI and OH^-
• D) H⁺only
• E) H₂O and OH^-
