Name: Chemistry 008, Spring 2008 Cornell University Dr. Pontrello Due 2/17/08 Learning Strategy Questions 3 Any time you write down a number, please include correct units when applicable. Clearly write any equation(s) that you are using to answer each question, and also clearly indicate the steps used to answer the questions, if appropriate. Part I: Calculating a Rate Constant. I.1 (14 points) The following table of data was collected for the N 2 O 5 reaction at 30.0 o C. N 2 O 5 (g) 2 NO 2 (g) + ½ O 2 (g) time (s) [N 2 O 5 ] (M) 7200 0.80 8600 0.72 9400 0.68 10800 0.58 Using the graph, plot the data in such a way as to verify that the reaction is first order. Using your plotted data, calculate the value of the rate constant, k.

Unformatted text preview: time (x 10 3 s) Name: 2 Part II: Calculating the Activation Energy. II.1 (18 points) The same reaction from Part I was monitored at different temperatures, and rate constants were determined as done in Part I. These data are presented in the following table. N 2 O 5 (g) → 2 NO 2 (g) + ½ O 2 (g) T (K) k (s-1 ) 318 5.0 x 10-4 308 1.4 x 10-4 298 3.5 x 10-5 Using the data from the table above, the value of k you calculated in Part I, and the graph below, calculate the activation energy (E a ) of the reaction. II.2 (10 points) What is the half-life of the reaction at 298 K? Show derivation of the equation starting with the integrated rate law....

### 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.
