Question
Chapter 19, Problem 43QAP
Interpretation Introduction
Interpretation:
Interpret dating of archaeological artefact using carbon -14.
Concept Introduction:
Radiocarbon dating is the method of indentifying the age of object which contains organic matter. This property uses the properties of radiocarbon. This technique work by measuring the content of carbon-14 present in matter and thus the age can be determined.

the current density:
1. at low fields is linear 2. at higher fields, it follows Tafel's law

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.
