Consider a series of reactions having the following energy profiles:
(1)
15 kJ/mol
-10 kJ/mol
25 kJ/mol
-15 kJ/mol
(3)
20 kJ/mol
5 kJ/mol
a) Rank the forward rate constants from smallest to largest (A <B) assuming
all 3 reactions have nearly the same value for the frequency factor A.
b) Imagine that these reactions are reversed. Rank these reverse reactions
from slowest to fastest (A<B).
