Question 1

What does the initial rates method help chemists determine?

  • The final product
  • The order of the reaction
  • The reaction temperature

💡 Hint: Consider what aspect of the reaction this method focuses on.

Question 2

True or False: The concentration of all reactants must be changed simultaneously to determine reaction order.

  • True
  • False

💡 Hint: Think about the importance of controlling variables.

Challenge Problems

Push your limits with challenges.

Question 1

Design an experiment to determine the reaction order of a hypothetical reaction A + B → C. Explain how you would systematically vary concentrations and analyze results.

💡 Hint: Think of how controlling variables can help isolate reactions.

Question 2

Given the following data from initial rate experiments:
Experiment 1: [A]=0.1 M, [B]=0.2 M, Rate=0.01 M/s;
Experiment 2: [A]=0.1 M, [B]=0.4 M, Rate=0.04 M/s;
Analyze the data to determine the order of reaction with respect to B.

💡 Hint: Look for multiplicative relationships in rates when concentrations change.
