![Highlight, copy, and paste the Excel Arrhenius Plot for the S20 and I reaction into your lab report where
indicated. The plot should resemble the example shown above. At minimum the plot, must have the following
features:
1. A Title = Arrhenius Plot
2. Axis Labels: y-axis = In k and x-axis = 1/T (1/K)
3. Trendline (see dotted line above) and Trendline Equation
Calculation - Energy of Activation (E,)
Using the slope from the Arrhenius plot, R [8.31 J/(mol-K)], and the equation below, calculate the value of
the E, for the reaction of S;Og* and I in J/mol and kl/mol.
E, = -(R)(slope)
