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.

Arsenic (As) is extremely toxic in its many forms and oxidation states. In nature, especially in groundwater, it is found in the form of arsenate (AsO ₄ ³ ⁻ ), which can be electrochemically reduced to As ⁰ and collected at the cathode of a coulometric cell. In this case, Potentiostatic Coulometry (at 25°C) was performed in an alkaline medium (pH = 7.5 throughout the analysis) to quantify the species. What potential (E) should have been selected/applied to perform the analysis, considering that this is an exhaustive electrolysis technique (until 99.99% of all AsO ₄ ³ ⁻ has been reduced to As ⁰ at the electrode, or n( final) = 0.01% n( initial )) and that the concentration of AsO ₄ ³ ⁻ found in the initial sample was 0.15 mmol/L ?
