Most reactions occur by a series of steps. The energy profile for a certain reaction that proceeds by a two-step mechanism is 

On the energy profile, indicate 

a. The positions of reactants and products.

b. The activation energy for the overall reaction.

c. ΔE for the reaction.

d. Which point on the plot represents the energy of the intermediate in the two-step reaction?

e. Which step in the mechanism for this reaction is rate determining, the first or the second step? Explain.
