Journal Entry:

NO₂(g) and F₂(g) can react to produce NO₂F(g), as represented above. A proposed mechanism for the reaction has two elementary steps, as shown below.

Draw a reaction energy profile that represents this proposed mechanism.

Learning Intentions

• We will learn how to apply concepts about reaction rates to released free response questions.  

Closing Task:

You can answer free response questions about reaction rates.

Content Standards being covered:

Catalysts function by lowering the activation energy of an elementary step in a reaction mechanism, and by providing a new and faster reaction mechanism. (E.K. 4.D.1)

Important classes in catalysis include acid base catalysis , surface catalysis, and enzyme catalysis. (E.K. 4.D.2)
