SUMMARY
The rate law for the reaction 2A + B2 → 2AB is defined as Rate = k[A][B2]. The proposed mechanism involves two elementary steps: the first step is A + B2 → AB + B, followed by B + A → AB. This mechanism aligns with the rate law, indicating that the slow steps involve one mole of A and one mole of B2, confirming the stoichiometry of the rate law. The discussion emphasizes the importance of understanding reaction mechanisms in relation to rate laws.
