Multiple Choice
Which statement best describes an effect of using a catalyst in an industrial process?
A
A catalyst increases the equilibrium constant of the reaction.
B
A catalyst is permanently altered and cannot be reused after the reaction.
C
A catalyst increases the rate of reaction without being consumed in the process.
D
A catalyst changes the products formed in the reaction.
Verified step by step guidance1
Understand the role of a catalyst in a chemical reaction: a catalyst provides an alternative reaction pathway with a lower activation energy, which increases the rate at which equilibrium is reached.
Recall that a catalyst does not affect the position of equilibrium, meaning it does not change the equilibrium constant (\(K\)) of the reaction.
Recognize that a catalyst is not consumed or permanently altered during the reaction; it can be reused multiple times.
Note that a catalyst does not change the products formed; it only affects how quickly the reaction reaches equilibrium.
Conclude that the best description of a catalyst's effect is that it increases the rate of reaction without being consumed in the process.
