Problem # 3 (a) Describe the forces responsible for formation of inert gas (such as Argon) crystals. Express the cohesive energy (U(R)) of such crystals as a function of interatomic distance R, and sketch U(R) vs R. (b) Evaluate the Madelung constant for a one-dimensional lattice of Na* and Cl ions. The distance between two nearest neighbor Na* and Cl ions is R. (c) For H2 one finds from measurements on the gas that the Lennard – Jones parameters are ɛ = 40 x 10-16 erg and o = 2.91 Ả. Find the cohesive energy in kJ per mole of H2. Assume that the H2 molecules for an fcc lattice. Treat each H2 molecule as a sphere.
