Question 1

What is the purpose of the initial rates method?

  • To determine products formed
  • To find reaction orders
  • To calculate energy changes

💡 Hint: Consider what happens when you vary concentrations.

Question 2

True or False: A reaction is first order with respect to a reactant if doubling its concentration quadruples the rate.

  • True
  • False

💡 Hint: Think about the meaning of order in kinetics.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a reaction where doubling the concentration of Reactant X results in a tripling of the rate. What is the order with respect to Reactant X? Justify your answer.

💡 Hint: Think about how changes in concentration translate into changes in reaction speed.

Question 2

You conducted an experiment and observed the following rates: [A] = 0.1 M, Rate = 2.0; [B] = 0.1 M, Rate = 2.0. If you modified the concentration of A to 0.2 M and the rate became 4.0, what can you say about the order concerning A?

💡 Hint: Examine how the concentration changes influence the reaction rate.
