Pre-Lab Questions read CHEM201 40613 4. A student determined ined AlHaven for the reaction of sodlium hydroside aed ur described in this module. The student added 100.0 ml. of 0as0o M N Pre-Lab Questions 100.0 ml of 0.8404 M acetic acid at 5 minutes. Prioe to and following the mixing the graphing guide as needed) to answer the Na011 o its) to all questions! of the aci time data were collected. Plot the data following questions. Show work (with Time Temperature, ℃ min NaOH me T 17.52 min mixture 0.5 1.0 17.54 6 23.28 7 23.03 17.73 8 23.10 9 23.06 10 22.99 11 22.93 12 22.89 13 22.85 14 22.78 17.75 2.0 17.55 2.5 3.0 17.57 3.5 4.0 17.58 4.5 5.0 mixing 17.78 7.80 mixing 15 22.73 16 22.70 17 22.64 18 22.59 a. Plot the data and add trendlines. Attach a copy of the graph to your pre-lab b. From the graph, determine AT i. Determine the temperatures of the unmixed reactants right before mixing x min) using the trendlines of the graph. i. Using the values in part i, calculate average temperature of the unmixed reactants (right before mixing). 7,601 35140 ii. Use the answer to part ii as your initial temperature to calculate AT of the reaction mixture. Note: you need to calculate the final temperature Enthalpy 2 17.64-17,70D 56
