Question
Progress of the reaction 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. Which is the more stable intermediate? g. What is the reactant of the rate-determining step? h. Is the first step of the reaction exergonic or endergonic? i. Is the overall reaction exergonic or endergonic? 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) In two, at points C and E the valley in the energy diagram represents the intermediates.
b) In the transition state is the point of highest energy between the reactant(s) and product(s).
B, D and F are represents the transition states.
c) E to G through F is the fastest step beacause of low activation energy at point F.
d) G is more stable because it has lower energy than A.
e) A is formed faster than E from C because of less activation energy at B
f) C is most stable intermediate because of less energy.
g) First step of reaction is endergonic and delta G is positive.
h) The overall reaction is exergonic and delta G is negative.
i) E to G has largest rate constant
j) E to C has smallest rate constant
K)G to E step in the reverse direction has the smallest rate constant.
