Challenge Problems
Push your limits with challenges.
Question 1
For a reaction with a rate law Rate = k[A]^2[B], if the concentration of A is doubled and the concentration of B is halved, what is the new rate compared to the original rate?
💡 Hint: Follow the changes in concentration using the original rate expression.
Question 2
A zero-order reaction has a rate constant of 0.04 M/s. What will be the concentration of the reactant after 10 seconds if the initial concentration was 1 M?
💡 Hint: Remember the zero-order reaction formula relates concentration decrease to time.
