Challenge Problems
Push your limits with challenges.
Question 1
Given the reaction 2A + B → 3C, identify the molecularity of each step if the mechanism is composed of two elementary steps, the first is A + B → D (slow) and D → C (fast). What are the implications for the reaction order?
💡 Hint: Identify molecularities first; then look at the slower step.
Question 2
Discuss why a reaction featuring a termolecular mechanism might show a slower rate compared to a bimolecular mechanism, even with similar concentrations.
💡 Hint: Think about the probability of particle collisions.
