What does the rate law express?
💡 Hint: Focus on what influences reaction speed.
True or False: A second-order reaction's rate is proportional to the concentration squared.
💡 Hint: Consider how changes in concentration would affect the rate.

Challenge Problems
Push your limits with advanced challenges
For a reaction with a rate law of Rate = k ⋅ [X]^2 ⋅ [Y]^1, if [X] is increased by a factor of 3 and [Y] is decreased by a factor of 2, what will be the overall effect on the reaction rate?
💡 Hint: Consider how both concentration changes interact with respect to the rate law.
If it is determined that the order of a reaction with respect to a reactant A is 3, calculate the effect on the rate if [A] is halved.
💡 Hint: Remember, the order of 3 means you raise the halved concentration to the power of 3.
