Post-Lab Questions
1. Detemrine the order of the IKI in this reaction?
2. Determine the order of the H2)2 in this reaction?
3. Calculate the rate law constant.
4. WHat is the overall rate law?
5. When finding the order of H2O2, why was Trial 1 and Trial 3 used?
6. When finding the order of IKI, why was trial 1 and Trial 2 used?
7. Research and identify some alternative catalysts that could be used to accelrate the decomposition of hydrogen peroxide. Evaluate these catalysts and determine which option is "greener".
Explanation / Answer
H2O2 .....I^-.......> H2O + O2
KI can act like a catalyst
1. Detemrine the order of the IKI in this reaction?
0 order
2. Determine the order of the H2)2 in this reaction?
1st order
3. Calculate the rate law constant.
rate = K[H2O2]
4. WHat is the overall rate law?
1st order
5. When finding the order of H2O2, why was Trial 1 and Trial 3 used?
rate of the reaction can varies w.r.t. change in concentration of H2O2
6. When finding the order of IKI, why was trial 1 and Trial 2 used?
because rate of the reaction can varies w.r.t. change in concentration of KI
