By using photons of specific wavelengths, chemists can dissociate gaseous HI to produce H atoms with certain speeds. When HI dissociates, the H atoms move away rapidly, whereas the heavier I atoms move more slowly. Given that the bond energy of H-I is 300.4 kJ/mol, what is the longest wavelength (in nm) that can dissociate a molecule of HI?
By using photons of specific wavelengths, chemists can dissociate gaseous HI to produce H atoms with certain speeds. When HI dissociates, the H atoms move away rapidly, whereas the heavier I atoms move more slowly. Given that the bond energy of H-I is 286.1 kJ/mol, what is the longest wavelength (in nm) that can dissociate a molecule of HI?
By using photons of specific wavelengths, chemists can dissociate gaseous HI to produce H atoms with accurately known speeds. When HI dissociates, the H atoms move away rapidly, whereas the relatively heavy I atoms move little. Use Table 9.2 in your textbook to answer the following questions: (a) What is the longest wavelength (in nm) that can dissociate a molecule of HI? 4.9) 406 nm (b) If a photon of 226 nm is used, what is the excess energy (in...
1. The 1-1 bond of iodine (12) can be broken (creating two separate I atoms) with electromagnetic radiation. What is the longest wavelength (lowest energy) photon which has sufficient energy to break the 1-1 bond if the energy of the bond is 151 kJ mol'? (show all work, 4 pts) b) Would a photon of this wavelength be best characterized as X-ray, microwave, or infrared electromagnetic radiation? (1 pt) 2. Consider a green laser that emits photons at 532 nm....
If you have 1 mol of HBr molecules, and you have a source of 269.7 nm photons that you can use to dissociate those bonds. What is the excess energy (given in eV) that 1 mole of those photons carry over what is needed for the dissociation of the bonds? Give answer in eV/mol 1 eV = 1.6022x10-19 J Average Bond Energles (kJ/mol) and Bond Lengths (pm) Table 9.2 Energy Length Bond Energy Length Bond Bond Length Bond Length Energy...
