Consider the Reaction Free-Energy Diagram for Two Reactions That Convert

Multiple Choice

Consider the reaction free-energy diagram for two reactions that convert reactants (R) into products (P) and select the two correct statements.

A) Reaction 1 is faster because it occurs in one step.
B) Reaction 2 is faster than reaction 1.
C) Both reactions occur at the same rate at a given concentration of R.
D) X is a transition state of reaction 2.
E) The rate-limiting step of reaction 2 is R ⇌ X.f.
The rate-limiting step of reaction 2 is X ⇌ P.g.
X must be a carbocation.
