1034 STUDY GUIDE Page 1 The final exam is divided into two parts: A. Part I General Knowledge 60 points B. Part II Problem Solving 40 points Part I General Knowledge 60 questions (1 point each) These multiple choice questions will come from Experiment 1 (Beer’s Law/Aspirin) through Experiment 10 (Gibbs Free Energy/Borax). You should be familiar with the equipment used; how the equipment was set up and calibrated; how LabQuest was used to obtain data such as the slope of a straight line; the basic procedural steps followed in each experiment. For experiments that involved graphical analysis, you should know what was plotted on each axis; what the graphs looked like; what was obtained from the graphs. These multiple choice questions do not involve any calculations. Part II Problem Solving 10 questions (4 points each) Problems will involve similar calculations to those you did as part of the data analysis and post-lab exercises for experiments 1 through 10 (except the Le Châtelier’s Principle lab). 1. Use a Beer’s law plot to obtain concentration given the absorbance of a solution, along with the dilution equation. 2. Calculate the enthalpy of vaporization from vapor pressure and temperature data. 3. Calculate the molar mass of a solute given freezing points of solute and solution, along with masses. 4. Determine the order for each reactant given initial concentrations and rates for a kinetics experiment. 5. Calculate the activation energy for a decomposition reaction given an Arrhenius plot and the equation of the straight line. 6. Calculate the pH of a buffer solution given pKa values and concentrations of the acid and conjugate base. 7. Calculate the molarity of an analyte given acid-base titration data such as molarity of titrant and equivalence points. 8. Calculate the molar mass of an analyte given titration data such as molarity of titrant and equivalence point. 9. Calculate enthalpy, entropy and Gibbs free energy of a dissolution reaction given Ksp and temperature data. Part III Bonus Questions (20; 1 point each): 10. This section will consist of general knowledge questions dealing with A. Excel (DeVicaris Only) B. the concept of precision as related to glassware as well as probes used in the course C. identifying Lab Quest icons and their use D. application questions which require no mathematical calculations 1034 STUDY GUIDE Page 2 SUMMARY OF EXPERIMENT  #### You've reached the end of your free preview.
