For the Following Reaction a + B $\rightarrow$ C + D, the Rate Law Is Determined to Be

Short Answer

For the following reaction A + B $\rightarrow$ C + D, the rate law is determined to be Rate = k[A]²a) Of the five proposed mechanisms shown below, which is consistent with the experimentally determined rate law?
1. 2 A $\rightarrow$ Z (slow)2 B + Z $\rightarrow$ 2 C + 2 D (fast)
2. A + B $\rightarrow$ C + D (slow)
3. 2 B $\rightarrow$ N (slow)2 A + N $\rightarrow$ 2 C + 2 D (fast)
4. A $\rightarrow$ X (slow)B + X $\rightarrow$ C + D (fast)
5. B $\rightarrow$ M (slow)A + M $\rightarrow$ C + D (fast)b)
Are there any intermediates in the mechanism you chose and if so what?
