Textbook Question
Chapter 5, Problem 5.86QP
The 235U isotope undergoes fission when bombarded with neutrons. However, its natural abundance is only 0.72 percent. To separate it from the more abundant 238U isotope, uranium is first converted to UF6, which is easily vaporized above room temperature. The mixture of the 235UF6 and 238UF6 gases is then subjected to many stages of effusion. Calculate the separation factor, that is, the enrichment of 235U relative to 238U after one stage of effusion.

In a system with an anodic overpotential, the variation of ŋ as a function of
the current density:
1. at low fields is linear 2. at higher fields, it follows Tafel's law
Find the range of current densities for which the overpotential has the same
value as when calculated for cases 1 and 2 (maximum relative difference of
5% with respect to the behavior for higher fields). To which overpotential
range does this correspond?

- Using the Arrhenius equation, it is possible to establish the relationship between the rate constant (k) of a chemical reaction and the temperature (T), in Kelvin (K), the universal gas constant (R), the pre-exponential factor (A) and the activation energy (Ea). This equation is widely applied in studies of chemical kinetics, and is also widely used to determine the activation energy of reactions. In this context, the following graph shows the variation of the rate constant with the inverse of the absolute temperature, for a given chemical reaction that obeys the Arrhenius equation. Based on the analysis of this graph and the concepts acquired about the kinetics of chemical reactions, analyze the following statements: I. The activation energy (Ea) varies with the temperature of the system. II. The activation energy (Ea) varies with the concentration of the reactants. III.
