6. What are the units for the rate constant, k, in this reaction? Are rate constant units always the same for every different reaction? Explain. 7. It was mentioned in the handout that what we measure in this experiment is the (average) initial rate of the reaction. We measure the time it takes for the first 6.0 x 104 M of I3 to form, and get the rate by dividing the change in concentration (=6.0x104 M) by that time. After this, the reaction then continues. What happens to the rate? Explain your answer. 8. Why do you think we say that you should stop timing at "the first appearance of blue color"? (Think about the consequences if some people stopped at the first appearance, and others waited until the flask was totally blue.)
