Catalysts

Question 6 • Chemistry - SC3210 A-CR

Which statement describes a catalyst?

Answer
A
Catalysts appear as reactants in a chemical equation.
B
Catalysts are completely consumed by the reaction.
C
Catalysts provide a lower energy pathway for the reaction.
D
Catalysts speed up chemical reactions by increasing surface area.

Explanation

A catalyst speeds up a reaction by providing an alternative pathway with lower activation energy. It is not completely consumed, and increasing surface area is not what defines a catalyst. Therefore, the correct choice is “Catalysts provide a lower energy pathway for the reaction.”
