Consider the fictional reaction: which is catalyzed by reagent C. The rate of this reaction was monitored by looking at the disappearance of B under several different experimental setups at 298 K.
Experiment [A] (M) [B] (M) [C] (M) Rate of disappearance of B (M/s)
1 0.400 0.0500 0.0500 0.0063
2 0.300 0.0500 0.0500 0.004725
3 0.300 0.100 0.0500 0.004725
4 0.300 0.0500 0.100 0.00945
5 0.400 0.0500 0.200 0.0252
Given the previous information, which of the following situations would lead to a plausible reaction mechanism?
a. Step 2 as the rate determining step. Step 1 is a fast equilibrium step while step 3 is a fast step.
b. Step 3 as the rate determining step. All other steps fast steps.
c. Step 2 as the rate determining step. All other steps fast steps.
d. Step 3 as the rate determining step. Step 2 is a fast equilibrium step while step 1 is a fast step.
