The mechanism for the reaction 2H2O2(aq) ® 2H2O(l) + O2(g) in the presence of I–(aq) is proposed to be:
Step 1: H2O2(aq) + I–(aq) ® H2O(l) + OI–(aq)
Step 2: H2O2(aq) + OI–(aq) ® H2O(l) + O2(g) + I–(aq)
Which of the following species is an intermediate?
a. I–
b. H2O2
c. H2O
d. OI–
What is the intermediate? Please help :)?

✔ 最佳答案
Step 1: H₂O₂(aq) + I⁻(aq) → H₂O(l) + OI⁻(aq)Step 2: H₂O₂(aq) + OI⁻(aq) → H₂O(l) + O₂(g) + I⁻(aq)
An intermediate is a substance which is formed in an early step of the mechanism and then reacts in a later step.
OI⁻ is an intermediate because it is formed in Step 1 and then reacts in Step 2.
The answer: d. OI⁻
