Question
Chapter 14, Problem 14.119SP
Interpretation Introduction
(a)
Interpretation:
The chemical equation for the overall reaction needs to be determined.
Concept introduction:
Two reactions are given in the question. To get the overall reaction both the reactions are added. The equation that is obtained after summation of two equations is the overall equation.
Interpretation Introduction
(b)
Interpretation:
The molecule that acts as a catalyst or intermediate in the reaction needs to be identified.
Concept introduction:
A catalyst is a substance that speeds up the reaction although it does not consumed in the reaction. It lowers the activation energy of the reaction that results the product formation easier. In this way catalyst

In a study of the formation of HI from its elements,
H2(g) + 12(g) == 2HI(g) equal amounts of H2 and 12
were placed in a container, which was then sealed and
heated. (a) On one set of axes, sketch concentration vs.
time curves for H and HI, and explain how Q changes
as a function of time. (b) Is the value of Q different if [12]
is plotted instead of [H2]?
0.0784 moles of substance A is dissolved in water to make a 2.00 L solution. Then, substance B is added, without changing the
volume of the solution, and the following reaction takes place:
2A (aq) + 3B (aq) →2C (aq)
During the course of the reaction, concentration of A is monitored. After 100 seconds into the reaction, it was found that 0.0570
moles of A is remaining.
Calculate the rate of disappearance of A in the first 100 seconds of the reaction.
Hint: Since rate is defined as the change in molar concentration (mol/L) over time, start by calculating molarity of A in the
beginning of the reaction, and 100 seconds after.
rate =
A [A]

- Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter.
