Presentation Transcript

  1. CHEM 304 – 2/8/12 I.B. Stratospheric chemistry: Ozone - The Chapman Mechanism - cont. (w/ Embedded Fundamentals) -> Chemical Kinetics - Rates of Chapman reactions - Lifetimes - Start Photochemistry ? KEEP READING READ CH 1 QUIZ AVE = 19/20 (!)

  2. The Ozone “Layer” - it is not a “layer”

  3. Photochemical Reactivity: 3 KEY questions • What wavelength does molecule absorb? 2) What altitudes are they available at? 3) Does the radiation carry enough E to break a bond ? (almost always YES!)

  4. The Electromagnetic Spectrum
