(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) PPh
3 would yield the largest value of K
eq and △G for the reaction as compared to PMe
3 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.
