Question
- A. 5 g/s
- B. 5 g
- C. 10 g
- D. 2 g
Answer
5 g/s
Explanation
The correct answer is 5 g/s. This is correct because it matches the rate of reaction, reversible reaction, equilibrium, catalyst, or Le Chatelier concept tested by this approved Chemistry 8462 learning objective. The other options are incorrect because they change the quantity, unit, condition, graph interpretation, or chemical relationship in the question.
Common mistake
Misunderstanding the Effect of Concentration
Students often think that increasing concentration always leads to a faster reaction rate without considering the context of the reaction.
To fix this, students should analyze the specific reaction and understand that while higher concentration generally increases the rate due to more frequent collisions, other factors like temperature and surface area also play significant roles.
