(b) Describe the nature and origin of various forces existing between the atoms of a crystal. Explain the formation of a stable bond using the potential energy versus interatomic distance curve. Assume that the potential energy of two particles in the field of each other is given by U(R) = - R where A and B are constants. R9 (i) Show that the particles form a stable compound for R= R. = (9B/A)/8 (R, is equilibrium separation) i) Show that for stable configuration, the energy of attraction is nine times the energy of repulsion. 8A (iii) Show that the potential energy of the system under stable configuration is 9Re
There are two important isotopes of uranium, 235 U and 238 U ; these isotopes are nearly identical chemically but have different atomic masses. Only 235 U is very useful in nuclear reactors. Separating the isotopes is called uranium enrichment (and is often in the news as of this writing, because of concerns that some countries are enriching uranium with the goal of making nuclear weapons.) One of the techniques for enrichment, gas diffusion, is based on the different molecular speeds of uranium hexafluoride gas, UF6 . (a) The molar masses of 235 U and 238 UF6 are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their typical speeds vrms ? (b) At what temperature would their typical speeds differ by1.00 m/s? (c) Do your answers in this problem imply that this technique may be difficult?
A Kt and a Cl- ion are separated by a distance of 0.52 nm. Find the coulomb component of the binding energy at that distance. Give your answer in eV. Make sure to include the approriate sign. A positive binding energy would be the ions are unbound and a negative binding energy means they are bound. Round your answer to 2 decimal places. Add your answer
There are three atoms: A, B, and C. The graphs of potential energy for the pairs AB and BC are shown below (the scale of the axes is the same for both graphs). Which of the following statements is correct? If there is more than one, you must select all of them. r TH U (AB) The AB bond has a smaller magnitude of binding energy than the BC bond. Breaking the AB bond releases more energy than breaking the BC bond. The reaction A + BC -> AB + C is exothermic. U (BC) None of the statements is correct. 1
