Use the data on Table 1 to construct a linear y versus x graph of ln(1/time) versus 1/temperature(K) in Excel. The graph should have a title that indicates it is a plot of data for the linear form of the Arrhenius equation. Each axis should have a named quantity label and x-axis should additionally have a unit label. Attach to this graph to the report page.

2. Use the data on Table 1 to construct a linear y versus x graph of In(1/time) versus
1/temperature(K) in Excel. The graph should have a title that indicates it is a plot of data for
the linear form of the Arrhenius equation. Each axis should have a named quantity label and
x-axis should additionally have a unit label. Attach to this graph to the report page.
3. State the slope(with correct units and sign) of the line on the graph constructed in #2
4. Use the stated slope in #3 to determine the energy of activation in kilojoules per mol. Show
your work.
5. Using the trendline equation for your graph, predict the time that the reaction would take at
75°C. Explain your reasoning and/or show your work to obtain this number. Note that the y
value is In (1/time). Convert the y value to time for your answer by using inverse In and
determining the reciprocal.
