試題詳解

Ni⁰L₄+ CO⇌Ni⁰L₃CO + L
(A) The forward reaction is likely to go by the Dissociative ( D ) mechanism.
(B) The forward reaction should possess a large positive and a large negative .
(C) To obtain the △G for the reaction, you can measure rates of forward reaction at different temperatures to determine rate constants, and plot In k vs. I/T.
(D) PPh₃ would yield the largest value of K_eq and △G for the reaction as compared to PMe₃ and P(OEt)₃. This statement should be attributed to the electronic argument.
(E) The presence of higher concentration of CO should shift the equilibrium to the right.
