Concept explainers
Rust Iron and oxygen combine to form iron oxide, orrust. List the reactants and products of this reaction.

Interpretation:
The reactants and products of the reaction need to be listed.
Concept introduction:
A new substance formed in a chemical reaction, the reactant is the starting material and product is last substance. In any reaction, the reactant portion is written in left side and the product portion is written in right side.
Answer to Problem 47A
Sodium and chlorine are the reactants, whereas sodium chloride is formed product.
Explanation of Solution
The elemental state of sodium and chlorine react together and form sodium chloride or table salt. This is a chemical change because a new substance is formed. In the chemical reaction, the reactant, sodium and chlorine, is represented on the left side and the product is sodium chloride is represented on the right side. The chemical reaction is
It is an explosive reaction because sodium and chlorine are reacted together.
In a chemical reaction, the left side substance is called reactant and the right-side substance is called a product of the reaction.

- 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?

- The data for the potential difference of a battery and its temperature are given in the table. Calculate the entropy change in J mol-1 K-1 (indicate the formulas used).Data: F = 96485 C mol-1arrow_forwardIn a cell, the change in entropy (AS) can be calculated from the slope of the E° vs 1/T graph. The slope is equal to -AS/R, where R is the gas constant. Is this correct?arrow_forwardUsing 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. The rate constant (K) varies proportionally with temperature. IV. The value of the…arrow_forward

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 ?
