(a)
Interpretation:
The given statement is true or false is to be determined. If false, the reason is to be explained.
(b)
Interpretation:
The given statement is true or false is to be determined. If false, the reason is to be explained.
(c)
Interpretation:
The given statement is true or false is to be determined. If false, the reason is to be explained.
Explanation:
The given statement is true, the catalyst gets reacted in the early step, and then is regenerated in a later step.
(d)
Interpretation:
The given statement is true or false is to be determined. If false, the reason is to be explained.
Explanation:
The given statement is false, because the intermediate is generated in the middle of the reaction and after being reacted with reactants gets converted into products, and is not being regenerated.
(d)
Interpretation:
The given statement is true or false is to be determined. If false, the reason is to be explained.

- By which of the following mechanisms does a catalyst operate? a. It decreases the activation energy barrier for a reaction. b. It serves as a reactant and is consumed. c. It increases the temperature of a reaction. d. It increases the concentration of reactants.arrow_forwardWhich reaction mechanism assumptions are unimportant in describing simple ionic reactions between cations and anions?

- 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_forwardIf a textbook defined a catalyst as "a substance that increases the rate of a reaction," would that definition be adequate?arrow_forward
