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?
