Question 1

Which of the following best defines a zero-order reaction?

  • A reaction where the rate increases with concentration
  • A reaction where the rate is constant regardless of concentration
  • A reaction where the concentration of reactants decreases exponentially

💡 Hint: Consider how rate and concentration interact.

Question 2

True or False: The half-life of a zero-order reaction depends on the initial concentration of the reactant.

  • True
  • False

💡 Hint: Think about how half-lives relate to reaction orders.

Challenge Problems

Push your limits with challenges.

Question 1

A zero-order reaction starts with a concentration of 4.0 M and has a rate constant of 0.2 M/s. How long will it take to decrease to 2.0 M?

💡 Hint: Use the integrated form to find the time.

Question 2

If a zero-order reaction's rate constant is 1.0 M/s, what is the effect on the half-life if the initial concentration is doubled?

💡 Hint: Think about how the initial concentration affects the half-life formula.
