Phys. 369, Fall 2009 Homework #6 - revised Due: Friday, Oct. 16, beginning of class 100 points total 1. (10 points) Schroeder, problem 4.1 2. (14 points) Schroeder, problem 4.5 3. (20 points) Schroeder, problem 4.6 4. (12 points) Schroeder, problem 4.14 5. (14 points) Schroeder, problem 4.18 6. (30 points) Gasoline is composed mostly of octanes, which are CH 3 (CH 2 ) 6 CH 3 molecules. Octanes exist in a variety of different geometries (different relative arrangements of the atoms) called isomers . Iso-octane, or 2,2,4 Trimethylpentane, is one of these isomers. Iso-octane has a standard heat of formation 259 kJ/mole f H Δ = − . Iso-octane is a liquid at standard temperature and pressure. a) Suppose that 2 moles of iso-octane and 25 moles of oxygen burn completely in the reaction 8 18 2 2 2 2C H +25O 16CO +18 H O (1) Find the change in the energy stored in chemical bonds from this reaction. b) Suppose now that iso-octane is mixed with air, such that the ratio of iso-octane to oxygen has the stoichiometric ratio of reaction (1), and that the iso-octane is in the vapor phase. (Of course,

### 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.
