Challenge Problems
Push your limits with advanced challenges
A reaction A + B ⇌ I (fast) → Products (slow) has an equilibrium constant K = 2. However, if the formation of I is slower than anticipated, how might this affect the accuracy of your rate constant calculations?
💡 Hint: Consider if the initial step shapes the outcome.
Construct a conceptual map demonstrating how the Pre-Equilibrium Approximation is utilized in complex kinetics and discuss the importance of each component in the mechanism.
💡 Hint: Link each component back to how it affects rate laws.
