Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What does it mean if a reaction is zero order with respect to a reactant?
💡 Hint: Think of how the concentration affects the rate.
Question 2
Easy
If doubling the concentration of a reactant doubles the rate, what order is it?
💡 Hint: Consider how directly proportional relationships work.

Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
If the reaction rate remains unchanged when a reactant concentration is doubled, what is the order of the reaction with respect to that reactant?
- First Order
- Zero Order
- Second Order
💡 Hint: Consider how concentration influences rate in different orders.
Question 2
True or False: A reaction that is second order with respect to reactant A will increase its rate by a factor of four if its concentration is doubled.
- True
- False
💡 Hint: Reflect on how second-order reactions operate.

Challenge Problems
Push your limits with challenges.
Question 1
You conduct an experiment and find that when you double the concentration of reactant X, the reaction rate becomes four times faster. If you then double the concentration of a second reactant Y while keeping X constant, and the rate increases by a factor of eight, what are the orders of the reaction with respect to X and Y?
💡 Hint: Analyze how the rate changes according to each reaction when you manipulate their concentrations.
Question 2
In a chemical reaction with multiple steps, you find that the rate law is Rate = k [A]^m [B]^n, but you only have data for [A]. If doubling [A] leads to quadrupling the reaction rate, while all other conditions remain constant, determine the value of m.
💡 Hint: Recall the relationship between concentration changes and how they affect the rate of reaction.
