Question
- A. 2 mol/s/s
- B. 3 mol/s/s
- C. 1 mol/s/s
- D. 4 mol/s/s
Answer
2 mol/s/s
Explanation
The correct answer is 2 mol/s/s. This answer directly addresses the question: If 12 mol of product is formed in 6 seconds, what is the mean rate of reaction in mol/s? 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
Incorrect Units for Rate of Reaction
Students often use incorrect units when calculating the rate of reaction, such as using grams instead of g.
Always ensure to express the rate of reaction in the correct units, such as g, c, or mol/s, depending on the context of the calculation.
