Answer the following questions n your Discussion. 1. The introduction of this experiment stated that, because you are timing the reaction essentially to completion, you are measuring the average rate of reaction versus an instantaneous rate of reaction. Why do you think t is important to make this distinction? How do you hypothesize that the rate of a chemical reaction would change over time? 2. What are other ways in which scientists can measure rates of reactions? Make sure to cite any outside Sources used to answer this question. 3. Why is t important that all the experiments performed were the same total volume? 4. What is the difference between the reaction rate and the rate constant? 5. Why was it important to perform multiple trials of each experiment? Does this make your data accurate or precise? Justify your answer. 6. How would the addition of a catalyst change the results obtained? Specifically, hg does a catalyst change the rate of a chemical reaction? Make sure to cite any sources used to answer this question. 7. What are some Sources of error that could have Occur in this experiment? How do these errors affect your results? How can you prevent these errors in the future?

Explanation / Answer

2. Other ways in which scientists can measure rates of reaction are:

(i). By measuring the amount of energy that has beeen given off after certain amounts of time and, if you know the enthalpy change of the reaction, you could measure the reaction rate.

(ii). Some scientists even use chromatography and make chromatograms of samples of the reaction mixture at time intervals to measure reaction rate. This kind of measurement is only used in very slow reactions.
