77. A reactant, R, can produce either of two products, P1 or P2, with
competing pathways, as illustrated in the reaction profile shown
right. If the reaction is carried out at low temperature, which of
the following best indicates the preferred product and the type of
control?
(A) Preferred product P1, kinetic control
(B) Preferred product P1, thermodynamic control
(C) Preferred product P2, kinetic control
(D) Preferred product P2, thermodynamic control
(E) Preferred product R, thermodynamic control
