Consider the following reaction.
3 A + B + 3 C 3 D + E
The following data was collected on the reaction.
Trial | [A]0 | [B]0 | [C]0 | Rate (M/s) |
1 | 0.41 | 0.45 | 0.41 | 1.543 |
2 | 0.82 | 0.45 | 0.41 | 6.172 |
3 | 0.41 | 0.9 | 0.41 | 3.086 |
4 | 0.41 | 0.45 | 0.82 | 1.543 |
Two mechanisms are proposed:
Mechanism 1:
A + C | D + Y | |
Y + C | X | |
X +2 A + B | D + Z | |
Z + A | E |
Mechanism 2:
B + C | D + Y | |
Y + B + C | X + D | |
X + A + C | E |
Which mechanism best fits the data?
Which is most likely the rate-determining step?
