Spring 2006 10.571 Atmospheric Chemistry and Physics Homework Problem Set Number 1 Assigned 28 February 2006 Due Date7 March 2006 (No later than 5:00 pm) Problem 1.1 – The Kyoto Protocol and its Relevance to Urban Air Pollution In class we have been discussing air pollution problems that range in scales from local to global. At present much of the discussion in newspapers, radio and TV is about global climate and in particular about the impact of carbon dioxide (CO 2 ). Prepare a one page summary of the Kyoto Protocol, be sure to address its organizational form, who are the signatories, what emission control options are being proposed etc. Once you understand the protocol discuss its relevance to solving urban scale photochemical air pollution problems. Please include the appropriate citations to web sites, papers, books that you use to prepare you memorandum. Problem 1.2 – Combustion Chemistry and Air Quality Standards The balanced chemical equation for the complete combustion of a general hydrocarbon fuel C x H y is given by y C H y + x + 4 y O 2 xCO + H O x 2 2 2 (a) If 1.0 mole of C x H y is completely burned, show that 3.7[x + (y/4)] moles of (unreacting) nitrogen will be contained in the emissions. Hence, write an expression, in terms of x and y , for the total number of moles of gases in the emissions.

    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.
