In the context of organic chemistry reactions, which of the following best describes the role of a catalyst?
A
A catalyst increases the rate of a reaction without being consumed.
B
A catalyst is consumed in the reaction to form the final product.
C
A catalyst changes the equilibrium position of a reaction.
D
A catalyst decreases the activation energy by forming a permanent bond with the reactants.
Verified step by step guidance1
Understand the definition of a catalyst: A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change itself.
Recognize that a catalyst works by providing an alternative reaction pathway with a lower activation energy, which speeds up the reaction.
Clarify that a catalyst is not consumed in the reaction; it remains unchanged after the reaction has completed.
Note that a catalyst does not change the equilibrium position of a reaction; it only helps the system reach equilibrium faster.
Understand that while a catalyst may temporarily interact with reactants, it does not form permanent bonds with them, allowing it to be reused in subsequent reaction cycles.
