Question
A reaction is studied and found to proceed in the following two elementary steps:
A + B C + Q
Q + A D + B
What is the intermediate for the reaction?
Q
A
B
D
C
2A B + C
The above reaction is studied and found to proceed in the following two elementary steps:
A Q
Q + A B + C
If the second step is the rate determining step (slow step), what is the rate law for the overall reaction?
rate = k
rate = k[A]2
rate = k[A]
rate = k[A]/[B][Q]
2A B + C
The above reaction is studied and found to proceed in the following two elementary steps:
A B + Q
Q + A C
If the first step is the rate determining step (slow step), what is the rate law for the overall reaction?
rate = k[A]2
rate = k[A]
rate = k[A]/[B][Q]
rate = k
Q
A
B
D
C
Explanation / Answer
1) intermediate for the reaction is "Q". (because Q only converted into products but not "C":)
2) rate = k[A]2
3) rate = k[A]
