Question 1

What is the initial rate of a reaction?

  • Speed at high concentrations
  • Speed at the beginning of a reaction
  • Slowest point in the reaction

💡 Hint: Focus on timing in regards to the reaction.

Question 2

True or False: A zero order reaction's rate is dependent on the reactant concentration.

  • True
  • False

💡 Hint: Reflect on how concentration variations affect speed.

Challenge Problems

Push your limits with challenges.

Question 1

You conduct an experiment showing that when [A] is doubled, and the rate increases by a factor of 2, while when [B] is doubled, the rate increases by a factor of 4. Determine the orders of the reaction with respect to [A] and [B] and write the rate law.

💡 Hint: Analyze how each change in concentration impacted the rate.

Question 2

During a reaction study, you notice that doubling the concentration of a reactant doesn't change the initial rate. What can you conclude about the reaction order with respect to that reactant, and why?

💡 Hint: Reflect on the independent characteristics of zero-order reactions.
