Kinetics of a Reaction Lab Report

Kinetics of a Reaction Lab report
State your name, then your partner’s name. Work in groups of two or three.

Prelab:
1. Why are reaction rates important?
2. Define:
A. Rate Law
B. Rate Constant
C. Activation Energy (Ea)
D. Catalyst
E. Reaction Rate
F. Reaction Order
3. Balance this redox reaction in an acidic solution: Iodide ions mixed with Bromate ions produce Bromide ions and Iodine.
4. What does the reaction rate depend on?
5. What 3 things have to be determined to find the total rate law?
6. How does the iodine produced in step #3 react with starch?
7. How will we measure the rate of iodine production?
8. What is activation energy used for?
9. How do catalysts work?
10. What is the purpose of each of the 4 parts of this experiment?
11. Complete Pre-Lab Questions 1-4.
12. Where can you mess up on this lab? Describe specifically.
13. Prepare data copies. Adjust part 1 to reflect using 50 drops instead of 5 drops to obtain their masses. We’ll need to add 50 drops at a time to a beaker to measure their masses.
14. In Part 2, which set of experiments vary [I-]? [H+]? [BrO3-]?
15. In all experiments, how do you know when to stop timing?
16. In Part 3, why is it necessary to first warm the KBrO3 pipette?
16. In Part 3, why is it necessary to dry the pipette?
