Interpretation Introduction
Interpretation:
The arrangement of compounds that corresponds to the increasing boiling point is to be stated.
Concept introduction:
The temperature at which a compound starts boiling is known as boiling point. The boiling point of any compound depends upon the different types of intermolecular interactions.

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.

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.
