CHEMISTRY 1AA3 March 29-April 2, 2010 TUTORIAL PROBLEM SET 11 ________________________________________________________________________ Chemistry 1AA3 1. The decomposition of N 2 O 5 in the gas phase at room temperature was studied. Using the following data verify that the rate law is first order in [N 2 O 5 ] and calculate the rate constant. Time (s) [N 2 O 5 ] (M) 0 0.100 50 0.0707 100 0.0500 200 0.0250 300 0.0125 400 0.00625 2. Using the data in the previous question, calculate [N 2 O 5 ] at 150 s after the start of the reaction. Since 150 s is half-way between 100 s and 200 s (two time points at which [N 2 O 5 ] was measured) is it possible to use the average of the two values to obtain the [N 2 O 5 ] at 150s? If your answer is no, explain why. 3. A certain first order reaction has a half-life of 20 min. a) Calculate the rate constant for the reaction. b) How much time is required for the reaction to be 75% complete? 4. Come up with an alternative way to solve question 3. Is the method you propose applicable for all reactions? 5. Stinker. For the following reaction: 2C 4 H 6 (g) C 8 H 12 (g)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
