3 cards from this section. Quick, good the night before a test.
What is molecularity?
Think about how many particles are involved in a single step of a reaction.
Can molecularity ever be a fraction?
Remember, how we count particles!
What is the highest value molecularity can take?
Remember, what's the maximum for a simple step?
True or False: Molecularity can be a fraction.
Think about how we count different species.
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?
Identify molecularities first; then look at the slower step.
Discuss why a reaction featuring a termolecular mechanism might show a slower rate compared to a bimolecular mechanism, even with similar concentrations.
Think about the probability of particle collisions.
