The ozone cycle that occurs in the stratosphere is responsible for the absorption of some of the high energy radiation emitted by the sun The photo dissociation of O2(g) is the first step in the ozone cycle. 02(g) + hv → 0(g) + 0(g) The bond dissociation energy of O2 is 495 kJ/mol I. What is the minimum energy a photon could have to be able to break this bond upon absorption? Il. What is the wavelength of the photon?...
Chemical dyes, which selectively absorb some wavelengths of visible light and appear with characteristic colors, are typically large molecules where the distribution of chemical bonds allows some electrons to travel easily from one end of the molecule to the other. These electrons are effectively confined to a one-dimensional box. The wavelengths of light absorbed by the molecule are then related to its length. If a particular dye has a length of 0.90 nm, determine the three longest wavelengths that the...
The reason there is danger in exposure to high energy radiation is that the radiation can rupture chemical bonds. In some cases cancer can be caused by it. A C-C single bond has a bond energy of aprox 348 kJ/mol. What wavelength ( in nm) of light is required to provide sufficient energy to break the C-C bond?
56) Calculate the longest wavelength of light (nm) that can be used to remove electrons from metal surfaces if 245 kJ/mol is required to eject electrons. (1.33pts) 0233 165 488 725 552
