Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the purpose of measuring the initial rate of a reaction?
💡 Hint: Consider why we measure right at the beginning of the reaction.
Question 2
Easy
If doubling the concentration of a reactant quadruples the rate, what is the order of that reaction with respect to that reactant?
💡 Hint: Reflect on the relationship between concentration change and rate change.

Question 1
What is the main purpose of the method of initial rates?
- To measure reaction time
- To determine the reaction order
- To calculate equilibrium concentrations
💡 Hint: Think about the importance of knowing how each reactant affects rates.
Question 2
In a rate law, what does the exponent on the concentration term represent?
- True
- False
💡 Hint: Recall the general format of a rate law.

Challenge Problems
Push your limits with challenges.
Question 1
Given a reaction A + B ⟶ C, you determine that when the concentration of A is doubled, the initial rate doubles; when the concentration of B is doubled, the rate increases by a factor of eight. Deduce the rate law for this reaction.
💡 Hint: Use the changes in rates to find each 'n' and 'm' separately.
Question 2
A mixture of reactants produces a gas that accumulates in a flask. You measure that the initial rate of production is 0.1 mL/s for [A] = 0.1 M and [B] = 0.2 M. If you increase [A] to 0.2 M while keeping [B] constant and the rate increases to 0.4 mL/s, what is the order of reaction with respect to A?
💡 Hint: Relate concentration changes directly to how the rate changes.
