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

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 =

- 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. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?arrow_forwardIndicate to which of the following types of reactions each of the statements listed applies: combination, decomposition, displacement, exchange, and combustion.

Forward and reverse reactions will continue until both reach a rate of zero. The rate of the reverse reaction increases as hydrogen gas accumulates.arrow_forwardIn an experiment, sulfuric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was formed during the reaction. A cross drawn at the base of each flask became gradually invisible due the formation of this yellow precipitate. The time taken for the cross to become invisible was recorded. A partial record of the experiment is shown. Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the experimental record. Use complete sentences to explain the trend you predicted.
