Challenge Problems
Push your limits with advanced challenges
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.
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.
