question 41

Multiple Choice

The mechanism for the reaction 2 H₂O₂ (aq) $\rightarrow$ 2 H₂O(l) + O₂(g) 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) What is the rate law for the overall reaction?

• A)k[H₂O₂]
• B)k[H₂O₂]²
• C)k[H₂O₂][I^-]
• D)k[H₂O₂][OI^-]
• E)k[H₂O₂]²[I^-]/[H₂O]
