Solution Summary: The author explains that the molarity of each of the elementary reactions should be determined. The rate constant is the proportionality term in the chemical reaction rate law.
Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

(a)
Interpretation Introduction
Interpretation: The molarity of each of the elementary reactions should be determined.
Concept introduction:
Molecularity: It is defined as the number of reacting species involved in a chemical reaction.
(b)
Interpretation Introduction
Interpretation: Rate equation of the reaction should be determined and decided whether it agrees with the given mechanism.
Concept introduction:
Rate law or rate equation: Rate law:
It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.
aA + bB→xXRate of reaction = k [A]m[B]n
Rate constant, k: The rate constant for a chemical reaction is the proportionality term in the chemical reaction rate law which gives the relationship between the rate and the concentration of the reactant present in the chemical reaction.
(c)
Interpretation Introduction
Interpretation: The concentration of the product should be determined after 5.0minutes.
Concept introduction:
Rate law or rate equation: Rate law:
It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.
aA + bB→xXRate of reaction = k [A]m[B]n
The integrated rate law for the first order is as follows:
There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
