- B. It is in a different phase from the reactants
- C. It is always a gas
- D. It is always a liquid
Answer
It is in a different phase from the reactants
Explanation
The correct answer is It is in a different phase from the reactants. This answer directly addresses the question: Which of the following best describes a heterogeneous catalyst? 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
Ignoring Catalyst Role
Students often forget that catalysts are not consumed in the reaction and can be reused.
Remember that catalysts facilitate reactions without being used up, allowing them to be reused multiple times.
