Question 1
Which of the following correctly describes a rate law?
- It states how temperature affects reaction rate.
- It expresses the relationship between reactant concentrations and reaction rate.
- It only applies to first-order reactions.
💡 Hint: Focus on how reactants influence the speed of reactions.
Question 2
True or False: The reaction orders in the rate law are always equal to the stoichiometric coefficients.
- True
- False
💡 Hint: Think about how experiments might show different behaviors.

Challenge Problems
Push your limits with challenges.
Question 1
A reaction has the following initial rates recorded for different concentrations:
1. [A] = 1M, [B] = 1M, Rate = 0.1 M/s
2. [A] = 2M, [B] = 1M, Rate = 0.4 M/s
3. [A] = 1M, [B] = 2M, Rate = 0.4 M/s
Determine the rate law for the reaction.
💡 Hint: Compare how each change in concentration alters the rate.
Question 2
Explain why the rates calculated from the initial rate method might differ from those calculated later in the reaction.
💡 Hint: Consider what happens as reactants are used up during the reaction.
