In CHEM123/125 lectures on the following topics,
Using the same reaction, but you cary out the experiment at different
temperatures to investigate the temperature effect on reaction rates.
The temperature effect is best described by the
Ea, defined in the Arrhenius equation
The Arrhenius equation is a model to correlate the rate constant k with temperature T. Many reactions follow this model, and it becomes a theory of chemical kinetics. You can apply the same technique to develop a scientific theory.
There lab skills you have acquired from Experiment 2 comes handy for this experiment. Lots of data are collected, and you are required to carry out extensive calculations from the results. The tables layed out in the Lab manual help you organize the information, and the organization of information is an important skill.
For the evaluation of Ea, the graphic method is suggested. Again, this is a useful technique, but modern computers may have other techniques to derive the same results. Feel free to investigate.
