Determine the activation energy, Ea, by plotting the natural log of k (In k) vs. the reciprocal of absolute temperature (1/T). Note: Absolute temperature, T= °C + 273. a. Choose New Calculated Column from the Data menu. b. Create a column, In rate constant, k. c. Create a second column, reciprocal of absolute temperature, 1/(Temperature (°C) + 273). d. On the displayed graph, plot In rate constants (In k) on the y-axis and the reciprocal of absolute temperature (1/T) on the x-axis by clicking on the respective axes labels. Autoscale the graph if necessary. Note: Attach this graph you created in your lab report as Figure 6 (title the graph properly). Describe the relationship between In k vs. 1/T. 2. Calculate the activation energy, Eo, for the reaction. To do this, first calculate the best fit line equation (linear fit) for the data in Step 2. Record the slope, m, of the linear fit below and use it to calculate the activation energy, Eo, in units of kJ/mol. Note: On a plot of In k vs. 1/T, Eg = m x R. 3. A well-known approximation in chemistry states that the rate of a reaction often doubles for every 10°C increase in temperature. Use your data to test this rule. (Note: It is not necessarily equal to 2.00; this is just an approximate value, and depends on the activation energy for the reaction.) CALCULATIONS: Slope, m : Activation Energy, Ea (kJ/mol) :,

You are a forensic scientist. You are investigating a murder involving poison. The victim was poisoned with a compound called di-chlorobenzene, whose formula is C6H4Cl2. Autopsy results show that the victim’s body contained about 27.5 g of the poison, but the actual amount could have been slightly higher due to tissue absorption. The main suspect is his wife, Suzanne, who works as a chemistry professor. Records show that she purchased 15 g of benzene (C6H6) two days before the murder. Benzene is one of the compounds use to make the poison. She claims she was using it to make methyl benzene (C6H5CH3), an innocuous compound, for use in her lab. She shows you the bottle of methyl benzene she claims to have made. It contains 25 g of methyl benzene. To produce di-chlorobenzene, the reaction is:       Cl2(g)  +  C6H6(l) ⟶⟶ C6H4Cl2(l) + H2(g) To produce methyl benzene, the reaction is:          CH4(g) + C6H6(l) ⟶⟶ C6H5CH3(l) + H2(g)   Use stoichiometry to solve this case. Be sure to show all…
