Challenge Problems
Push your limits with advanced challenges
You have a reaction with a first-order rate constant of 0.05 s⁻¹. How long will it take for the concentration of the reactant to decrease from 0.1 M to 0.025 M?
💡 Hint: Focus on the integrated form of the first-order rate equation.
For a zero-order reaction, if the initial concentration is 0.30 M and the rate constant is 0.10 M/s, calculate the time taken to reach a concentration of 0.15 M.
💡 Hint: Think about how zero-order affects the rate.
