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. The root mean square velocity of CO 2 gas (MW = 44.01) is approximately 15.1 m/s at 127C. True or false? Show your work! (03 pts) 2. If a reaction follows first order kinetics, then a plot of __________ versus time should be linear and the slope would be equal to: __________. (04 pts) 3. Assuming that time is measured in hours, what would be the units of the rate constant for a first order reaction? ______________. (02 pts) 4. Assume that we have two containers. One of these (20.0 L) is filled with nitrogen gas at a pressure of 1.231 atm at 300 K. The second container (10.0 L) is filled with nitrogen gas at a pressure of 2.053 atm at 250 K. The container that is closest to containing one mole of nitrogen gas would be (03 pts) a) The first container. b) The second container. c) They both contain one mole of nitrogen gas. 5. If we place 50.0 moles of oxygen gas in a 20.0 L flask at a pressure of 200 atm and a temperature of 900 K, the gas would exhibit predominantly attractive forces. True or false?...
