Question

A. They are included in the overall chemical equation for the reaction
B. They are consumed duringthe reaction
C. They can be reused multiple times
D. They only work at high temperatures

Answer

They can be reused multiple times

Explanation

The correct answer is They can be reused multiple times. This answer directly addresses the question: Which of the following statements is true about catalysts? 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 Reaction Profiles

Students often confuse the energy levels of reactants and products in catalysed and uncatalysed reactions on reaction profiles.

To fix this, students should practice sketching reaction profiles, clearly labeling the activation energy for both catalysed and uncatalysed pathways, and noting how the catalyst lowers the activation energy.
