In a hydrocarbon solution, the gold compound (CH3)3AUPH3 decomposes into ethane (C2H6) and a different gold compound, (CH3)AUPH3. The following mechanism has been proposed for the decomposition of (CH3)3AUPH3: Step 1: (CH3)3 AuPH; (CH3);Au + PH3 (fast) Step 2: (CH3)3 Au 4, C,H, + (CH;)Au (slow) Step 3: (CH3)Au + PH3 (CH3)AUPH3 (fast) (a) What is the overall reaction? (b) What are the inter- mediates in the mechanism? (c) What is the molecular- ity of each of the elementary steps? (d) What is the rate- determining step? (e) What is the rate law predicted by this mechanism? (f) What would be the effect on the reac- tion rate of adding PH3 to the solution of (CH3)3AUPH3?

Provide reasonable step-by-step mechanisms for the following reactions. Use arrows to indicate themovement of electrons.
[Rh(PPh3)3Cl] is a precatalyst that can be activated by dissociation of a phosphine ligand to form an active catalyst, B, which is used in the hydrogenation of alkenes. The active catalyst can then undergo oxidative addition in the presence of H2 to form complex C. Propene coordinates to C to form complex D, which then undergoes a 1,2- insertion step to form E. Reductive elimination of propane from E regenerates the active catalyst B. Draw complexes B – E and hence provide a full catalytic cycle, including the activation step, for the hydrogenation of propene
