Use the energy diagram pictured below to answer the following
questions. Be sure you explain your answers, so that we may all
learn from each other. Simply writing an answer as a single word
doesn't help your fellow classmates understand
why.

what letters represent intermediates? How can you recognize an
intermediate in a reaction diagram?
2. How many transition states are there in this reaction and
what letter are they...
