Help please, I got this so wrong on a test, and I don't know why!
![3. Hydrogen peroxide can decomposed into water and oxygen gas as described by the reaction below:
2H₂O2(aq) → 2H₂O(n + O₂(g)
AH = -196.1 kJ/mol
exo
A proposed mechanism for the reaction has three elementary steps shown below:
11
Step 1 H₂0₂ 20H
Step 2: H₂0₂ + O→ H₂O + H
Step 3: H+H₂O + 0₂
(fast)
a) Write a rate law for the overall reaction that is consistent with the proposed mechanism
