Calculate the average reaction time and reaction rate for each of the six temperatures {5 "C, 15 "C, 25 "C, 35 "E, and 45 "12}. Record the results in Table 1. 2. Calculate the rate constant k for each of the temperatures. Be sure to EhDW all calculations and include correct units for the rate constants. Record the results in Table 2. 3. Use a spreadsheet program [Excel or Google Sheets] to plot In h vs. 131'. The temperature must be in degrees Kelvin. Perform a linear regression to find the equation of the line. Make sure that the program prints the equation on the graph. Use the slope to determine the activation energy of the reaction. The value of the y—interoept can be used to estimate the value of Ina-'1'. and therefore a1. Record your results in Table 3. For assista one with making the graph, please see the Excel tutorial Making Graphs for Scientific Reports at the end of this document. 4.. In the spreadsheet program,r label the axes appropriately, including using where necessary. Make sure that the graph shows the linear regression, equation of the line, and R2 value. 5. Take a screen clip Use Commond—Shr?4 on o Mac or use the Shipping Tool on a PC. Do not take pull screen shots or photos of your computer screen. Resize the clip so that it ?ts on one page {portrait orientation]. Paste the graph under?gure I on page 6. 5. Answer the quations on the Post—Lab Worksheet.
