Chemical Kinetics Question 267
Question: A following mechanism has been proposed for a reaction
$ 2A+B\to D+E $ $ A+B\to C+D( slow ) $ $ A+C\to E( fast ) $ The rate law expression for the reaction is:
Options:
A) $ r=k{{[ A ]}^{2}}[ B ] $
B) $ r=k[ A ][ B ] $
C) $ r=k{{[ A ]}^{2}} $
D) $ r=k[ A ][ C ] $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] From slow reaction Rate =k[A][B]
