Part I: 30 points (report worksheet completed and handed in before leaving lab) Part II: 30 points (Lab notebook pages worth 5 pts - total for reports and notebook is 65 pts) Type sample calculations for determining H and S for n-pentane. ln(PV) = -(dH/R)(1/T) + (dS/R) slope = -dH/R = -3324.6 dH = 27642.387 J/mol dH = 27.64 kJ/mol Y-intercept = dS/R = 10.689 dS = 88.87 J/mol*K By signing below, you certify that you have not falsified data, that you have not plagiarized any part of this lab report, and that all calculations and responses other than the reporting of raw data are your own independent work. Failure to sign this declaration will result in 5 points being deducted from your report score. Signature: Laboratory Waste Evaluation (1 pt) Laboratory waste is considered anything generated during an experiment that is disposed of down the sewer drain, thrown in the garbage, collected in a container for disposal by the UW Environmental Health & Safety department, or released into the environment. Based on the written lab procedure and your actions during the lab, list the identity and approximate amount (mass or volume) of waste that you generated while performing this experiment. 0.01 M maleic acid solution 0.01 M fumaric acid solution 0.5 L DI water 1 trough ice cubes Paper towels Draw the structural formula for pentane: H H H H H H-C-C-C-C-C-H H H H H H Draw the structural formula for diethyl ether: H H H H H-C-C-O-C-C-H H H H H H Draw the structural formula for 2-butanone: H O H H H-C-C-C-C-H H H H Draw the structural formula for 2-butanol: H OH H H H-C-C-C-C-H H H H H Note: All secti this repo except t structur formulas be typed 0.00335 0.0034 0.00345 0.0035 0.00355 0.0036 0.00365 0.0037 -1.6 -1.4 -1.2 -1 -0.8 -0.6 -0.4 -0.2 0 f(x) = -3324.6302330552x + 10.6891663624 R² = 0.9853508834 Pentane: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm) 0.003300 0.003350 0.003400 0.003450 0.003500 0.003550 0.003600 0.003650 0.003700 -1.6000 -1.4000 -1.2000 -1.0000 -0.8000 -0.6000 -0.4000 -0.2000 0.0000 f(x) = -3309.4663662466x + 10.7184000366 R² = 0.9995192525 Diethyl Ether: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm) 0.002800 0.002900 0.003000 0.003100 0.003200 0.003300 0.003400 -2.5000 -2.0000 -1.5000 -1.0000 -0.5000 0.0000 f(x) = -3810.5172284734x + 10.7061006661 R² = 0.9997986729 2-Butanone: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm) 0.002750 0.002800 0.002850 0.002900 0.002950 0.003000 0.003050 -2.5000 -2.0000 -1.5000 -1.0000 -0.5000 0.0000 f(x) = -6180.2744377326x + 16.6854305709 R² = 0.9976497874 2-Butanol: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm)
