- Only typed explanation of both subparts otherwise leave itBy using photons of specific wavelengths, chemists can dis-sociate gaseous HI to produce H atoms with certain speeds.When HI dissociates, the H atoms move away rapidly, whereasthe heavier I atoms move more slowly. (a) What is the longestwavelength (in nm) that can dissociate a molecule of HI? (b) If aphoton of 254 nm is used, what is the excess energy (in J) overthat needed for dissociation? (c) If this excess energy is carriedaway by the H atom as kinetic energy, what is its speed (in m/s)?Two lasers generate radiation of (1) 9.5 µm and (2) 0.1 µm respectively.(a) For each of the radiations, determine the photon energy (in eV).(b) Will either of the two radiations be able to break (dissociate) the Si–H bondin SiH4? Given: ESi-Si = 180 kJ/moleEH-H = 435 kJ/mole
- Calculate the number of Schottky defects per m3 in KCl at 500oC. Energy required for the formation of each Schottky defect is 2.6 eV / atom, the density of KCl at 500oC is 1.995 g / cm3, k = 8.62x10-5eV / K.One important function of atomic and ionic radius is in regulating the uptake of oxygen by haemoglobin. for the change in ionic radius that accompanies the conversion of Fe(ll) to Fe(lll) when O2 attaches t riggers a conformational change in the protein. Which do you expect to be larger: Fe2+ or Fe3+? Why?Calculate the energy for vacancy formation in silver, given that the equilibriumnumber of vacancies at 800°C is 3.6x1023 m-3 . The atomic weight and density(at 800°C) for silver are, respectively, 107.9 g/mol and 9.5 g/cm3. (NA= 6.023x1023 atoms/mol)
- Use Born-Mayer equation to calculate the lattice energy for PbS (it crystallizes in theNaCl structure). Then, use the Born–Haber cycle to obtain the value of lattice energy for PbS.You will need the following data following data : ΔH Pb(g) = 196 kJ/mol; ΔHf PbS = –98kJ/mol; electron affinities for S(g)→S- (g) is -201 kJ/mol; ) S- (g) →S2-(g) is 640kJ/mol. Ionizationenergies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formationare calculated beginning with the elements in their standard states (S8 for sulfur). Diatomicsulfur, S2, is formed from S8 (ΔHf: S2 (g) = 535 kJ/mol. Can you just do the Born-Haber part?In 1995, Mario Molina, Paul Crutzen, and F. SherwoodRowland shared the Nobel Prize in chemistry for their work onatmospheric chemistry. One of several reaction sequences pro-posed for the role of chlorine in the decomposition of strato-spheric ozone is (1) Cl(g) +O3(g)→ ClO(g) +O₂(g) (2) ClO(g) +ClO(g)→ Cl₂O₂(g) (3) Cl₂O₂→ (g)2Cl(g)+ O₂(g).Over the tropics, O atoms are more common in the stratosphere:(4) ClO(g) +O(g)→ Cl(g) +O₂(g).(a) Which, if any, of these are oxidation-reduction reactions?(b) Write an overall equation combining reactions 1–3The average bond enthalpies of the C—F and C—Cl bondsare 485 kJ/mol and 328 kJ/mol, respectively. (a) What isthe maximum wavelength that a photon can possess andstill have sufficient energy to break the C—F and C—Clbonds, respectively? (b) Given the fact that O2, N2, andO in the upper atmosphere absorb most of the light withwavelengths shorter than 240 nm, would you expect thephotodissociation of C—F bonds to be significant in thelower atmosphere?
