Name (print)_________________________
Show your work for complete (and partial) credit. Report your answers to the correct
number of significant figures, and use units where appropriate.
1. The steps by which a reaction occurs, collectively, are called the
___________________________. Each step is called a/an
___________________________. The slowest step is called the
___________________________.Below, write an example of a unimolecular step. (A
generic reaction with A's and/or B's is OK).
2. For the reaction 2A + 2B ↔ A2B2, the rate law is
a) rate = k[A]2[B].
b) rate = k[A]2[B]2.
c) rate = k[A][B]2.
d) rate = k[B]2.
e) Not enough information is provided to decide.
3. Is it possible that the reaction A + 2B ↔ AB2 occurs in one step? Why or why not?
4. For the reaction A2 + 3B ↔ A2B3, the rate law is rate = k[B]2. Write a mechanism that
is consistent with this information.
