question 82

Multiple Choice

The mechanism for the first-order reaction 2 H₂O₂ (aq) $\rightarrow$ 2 H₂O(l) + O₂ in the presence of I^-(aq) is proposed to be:
Step 1: H₂O₂(aq) + I^-(aq) $\rightarrow$ H₂O(l) + OI^-(aq) (slow)
Step 2: H₂O₂(aq) + OI^-(aq) $\rightarrow$ H₂O(l) + O₂(g) +I^-(aq) (fast)
Identify the catalyst in the reaction.

• A)H₂O₂
• B)OI^-
• C)I^-
• D)H₂O
• E)O₂
