1. Example 3-1. Activation Energy. In the Excel spreadsheet, replace the value of kat 312.5 K with k = 0.0009's and detemine the new values of E and k. 2. Example 3-1. Make a plot of k versus T and In k versus (1/T) for E = 240 kJ/mol and for E = 60 kJ/mol. (1) Write a couple of sentences describing what you find. (2) Next, write a paragraph describing the activation energy and how it affects chemical reaction rates, and what its origins are. 1. Example 3-1. Activation Energy.
