Part C
For the reaction, 2A + B C, the following two-step mechanism has been proposed.
Step 1 2A D
Step 2 D+B C
If the first elementary step is the rate-determining step for the reaction, what is the predicted
rate law for the overall reaction?
> View Available Hint(s)
O Rate = k[A]²
O Rate = k[D]
O Rate = k[A]² [B]
O Rate = k[A]² B]

Part A
The following three-step mechanism has been proposed for the decomposition reaction,
2NO2CI(g) 2NO2(g) + Cl2 (g):
Step 1 2NO2C1(g) = Cl02(g) + N20(g) + CIO(g)
Step 2 N20(g) + CIO2(g) = NO2(g) + NOC1(g)
Step 3 NOCI(g) + ClO(g) → N02(g) + Cl2 (g)
Determine the molecularity for each of the elementary steps in order.
