Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the integrated rate equation for a zero-order reaction?
- [A] = [A]₀ - kt
- [A] = [A]₀e^(-kt)
- [A] = 1/[A]₀ + kt
💡 Hint: Remember that zero-order means the rate doesn't depend on concentration.
Question 2
True or False: The integrated rate equation for a first-order reaction can be expressed in logarithmic form.
- True
- False
💡 Hint: Consider how logarithms relate to exponential functions.

Challenge Problems
Push your limits with challenges.
Question 1
A first-order reaction has a half-life of 4 seconds. If the initial concentration was 2 M, what is the concentration after 12 seconds?
💡 Hint: Remember how to relate half-lives to concentration decreases.
Question 2
In a zero-order reaction where the rate constant is 0.05 M/s, calculate the time required for the concentration to decrease from 1 M to 0.4 M.
💡 Hint: Carefully rearrange the equation to isolate t.
