Question
- A. 1.6 g/s
- B. 1.6 g
- C. 2 g
- D. 1.5 g
Answer
1.6 g/s
Explanation
The correct answer is 1.6 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 Concentration Effects
Students often think that increasing concentration has no effect on the rate of reaction.
To fix this, remember that increasing the concentration of reactants usually increases the rate of reaction due to more frequent collisions between particles.
