Consider the three-step mechanism for the reaction of A through intermediates B and C to produce D shown below.

A → BEa = 15 kcal/mol, ΔH° = 13 kcal/mol
B → CEa = 10 kcal/mol, ΔH° = -6 kcal/mol
C → DEa = 2 kcal/mol, ΔH° = -20 kcal/mol

Which of the three steps is rate-limiting?

• The reaction of A to B.

• The reaction of B to C.

• The reaction of C to D.

• The most exothermic step is rate-limiting.

• All three steps occur at the same rate; there is no rate-limiting step.
