What is the rate law for a first-order reaction?
💡 Hint: Think about how the rate depends on the reactant.
True or False: The half-life of a first-order reaction is dependent on the initial concentration of reactants.
💡 Hint: Consider how half-life changes with different orders.

Challenge Problems
Push your limits with advanced challenges
A reaction has a rate constant k = 1.5 M/s. Determine how long it will take for the concentration to drop from 8 M to 4 M in a zero-order reaction.
💡 Hint: Remember to apply the zero-order integrated rate law correctly.
For a first-order reaction with a rate constant k = 0.1 s^-1, how long will it take for the concentration to decrease from 1 M to 0.5 M?
💡 Hint: Use the integrated first-order rate law for calculation.
