Question

how can i slove no.50? help!

Given the reaction coordinate diagram for the reaction of A to form G, answer the following questions: a. How many intermediates are formed in the reaction? b. Which letters represent transition states? c. What is the fastest step in the reaction? d. Which is more stable, A or G? e. Does A or E form faster from C? f. What is the reactant of the rate-determining step? g. Is the first step of the reaction exergonic or endergonic? h. Is the overall reaction exergonic or endergonic? i. Which is the more stable intermediate? j. Which step in the forward direction has the largest rate constant? k. Which step in the reverse direction has the smallest rate constant?

Explanation / Answer

a. Two intermediates C and E are formed in the given coordinate diagram of multiple transition complex reaction.

b. There are three transition states namely B, D and F. These are the point on the curve where the energy of the system is at its maximum.

c. In the step E to G, there is enough energy for the reaction to occur, hence, this reaction occurs rapidly.

d. G is more stable because it has lower energy than the reactants.
