Question 1
What is the average rate of disappearance of a reactant if it decreases from 0.20 M to 0.10 M over 10 seconds?
- 0.01 M/s
- 0.05 M/s
- 0.10 M/s
💡 Hint: Calculate the difference first.
Question 2
True or False: The instantaneous rate of a reaction is always greater than the average rate.
- True
- False
💡 Hint: Remember that instantaneous rate refers to a very brief moment.
