Question 1

Which of the following characterizes a zero order reaction?

  • Rate depends on concentration
  • Rate remains constant
  • Rate decreases over time

💡 Hint: Think about what happens to the rate when concentration changes.

Question 2

True or False: The half-life of a zero-order reaction is independent of its initial concentration.

  • True
  • False

💡 Hint: Recall the half-life equation you learned.

Challenge Problems

Push your limits with challenges.

Question 1

For the reaction A → Product, it was observed that the reaction rate was unaffected by the concentration of A during a test where [A] was initially 0.2 M and later reduced to 0.1 M. How can you explain the observed characteristics of this reaction? What implications does it have for catalyst design?

💡 Hint: Focus on the relationship between catalyst availability and rate.

Question 2

A zero order reaction starts with an initial concentration of 10 M and has a rate constant of 5 M/s. Calculate the time taken for the concentration to fall to 4 M.

💡 Hint: Use the integrated form to derive time from concentration change.
