Question 1

What is the average rate of reaction?

  • a) The rate at a precise moment
  • b) The rate over a time interval
  • c) The maximum rate observable

💡 Hint: Consider the distinction we discussed between timeframes.

Question 2

True or False: The units of reaction rate can differ based on the state of matter of the reactants.

  • True
  • False

💡 Hint: Is the unit constant across different phases of matter?

Challenge Problems

Push your limits with challenges.

Question 1

Given the concentration of a reactant over 3 time intervals: 0.10 M, 0.08 M, and 0.06 M over the times 0 s, 50 s, and 100 s respectively, calculate the average rate over the first interval.

💡 Hint: Break down the concentration change over the respective time.

Question 2

An instantaneous rate is observed as 0.002 M/s at 30 seconds for a reaction. If the concentration at 30 seconds was 0.15 M, what would the new concentration be after 10 seconds?

💡 Hint: Use the instantaneous rate to guide concentration changes over a time frame.
