- A. 72%
- B. 68%
- C. 64%
- D. 60%
Answer
72%
Explanation
The correct answer is 72%. This answer directly addresses the question: If the theoretical yield of a reaction is 20.0 g and the actual yield is 14.4 g, what is the percentage yield? 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 Endothermic and Exothermic Reactions
Students often confuse endothermic and exothermic reactions when predicting product yield based on temperature changes.
To fix this, remember that increasing temperature favors the endothermic direction, which can increase product yield, while decreasing temperature favors the exothermic direction.
