Unformatted text preview: Review, Chapter 2 • Application of the Arrhenius Equation, see problem 10, Chapter 2. In order to form a polymer, many identical small molecules are linked together in a chemical reaction. The polymerization reaction is exothermic, or heat producing, and it can be described as an Arrhenius process. The activation energy is typically on the order of 80 kJ/mol. How much does the reaction rate change if the temperature increases 10ºC? • Radius ratio range for an ionic material as a function of coordination number. Review, Chapter 3 • Packing factors and how they are calculated. • Calculations- one atom/lattice point to determine either density or atomic radius • Compare the planar densities in the BCC and FCC structures and which planes have the highest PF. • Directions and planes- how do we determine the Miller indices in simple systems? • Primitive/Non-primitive unit cells how are the volumes related?...
