Final answer:
The rate law for the elementary termolecular reaction A + 2B ⟶ products is Rate = k[A][B]².
Step-by-step explanation:
The rate law for the elementary termolecular reaction A + 2B ⟶ products is:
In this reaction, one molecule of A and two molecules of B are involved.
The rate of the reaction is proportional to the concentration of A and the square of the concentration of B.
