Chemistry 111 Page 1 out of 7 Exam III /Fall 2003 ID Number: _____ _____ - _____ _____ _____ _____ (LAST six digits only!) Instructions . Failure to show work will result in zero points being awarded in any question, unless it actually requires no work. If a blank is provided for an answer, you must enter your answer in that blank. 1. If the reaction: A Products… follows second order kinetics, then a plot of [A] versus time would be linear. True or false? Circle your answer. (02 pts) 2. Going back to the first question, a plot of ln[A] versus time would be linear. True or false? Circle your answer. (03 pts) 3. If the time is measured in minutes, what would be the units of k in the first question? Write your answer in the blank. (03 pts) Answer: __________________________ 4. Which of the following would have the largest value for b in the Vander Waals equation of state? (03 pts) CH 3 CH 2 CH 3 CH 3 C(CH 3 ) 2 CH 3 CH 3 CH 3 CH 4 For questions 5-8 , consider three identical tanks kept under the exact conditions of temperature and pressure. One contains SO 2 (MW = 64), another contains O 2 (MW = 32) and the last one has CH 4 (MW = 16). 5. Which of these gases would have the highest average kinetic energy? (03 pts) Answer: __________________________ 6. Which of these gases would have the fastest root mean square velocity? (03 pts) Answer: __________________________ 7. The density of the gases in the tanks gets halved as we compare SO 2 to O 2 and once more when we compare O 2 to CH 4 . True or false? Circle. (03 pts) 8. The rms velocity of the CH 4 is two times faster than the rms velocity of the SO 2 gas. True or false? Circle.
