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 being consumed in the process.
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, meaning it is not permanently altered or used up during the reaction.
Note that a catalyst does not shift the equilibrium position of a reaction; it only helps the system reach equilibrium faster.
Conclude that the correct description of a catalyst's role is that it increases the rate of a reaction without being consumed.
