Question

The iodide-catalyzed decomposition of hydrogen peroxide is thought to proceed by a four-step mechanism:

H2O2(aq) + I-(aq) --> HOI(aq) + OH-(aq) (slow)
HOI(aq) + OH-(aq) --> H2O(l) + OI-(aq)
OI-(aq) + H2O2(aq) --> HOOI(aq) + OH-(aq)
HOOI(aq) + OH-(aq) --> H2O(l) + O2(g) + I-(aq)



(a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process.


Rate = k [HOI] [H2O2]
Rate = k [H2O2]2    
Rate = k [I-] [H2O2]
Rate = k [H2O2]2 [H2O2]
Rate = k [I-] [HOI]
Rate = k [H2O2] [H2O2]





(b) Choose the correct chemical equation for the overall process.


HOI(aq) + OH-(aq) --> H2O(l) + OI-(aq)
H2O2(aq) + I-(aq) --> HOI(aq) + OH-(aq)  
  2 H2O2(aq) --> 2 H2O(l) + O2(g)





(c) Identify an intermediate in the reaction.
