Question

A. catalysts are included in the overall chemical equation for the reaction
B. catalysts provide a different reaction pathway with lower activation energy
C. catalysts are consumed duringthe reaction
D. catalysts increase the activation energy required for a reaction

Answer

catalysts provide a different reaction pathway with lower activation energy

Explanation

The correct answer is catalysts provide a different reaction pathway with lower activation energy. This answer directly addresses the question: Which of the following statements about catalysts is true? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.

Common mistake

Misunderstanding catalyst usage

Students think a catalyst is consumed during the reaction and therefore must be added in excess

Explain that a catalyst is not used up; it is only temporarily involved in the reaction pathway and can be recovered unchanged after the reaction
