Chemical Kinetics Question 49
Question: The reaction, $ X+2Y+Z\to N $ occurs by the following mechanism
(i) $ X+Y\rightarrow M $ (very rapid equilibrium) (ii) $ M+Z\to O $ (slow) (iii) $ O+Y~\to N $ (very fast) What is the rate law for this reaction-
Options:
A) Rate = k[Z]
B) Rate = k[X] $ {{[Y]}^{2}} $ [Z]
C) Rate = k[N]
D) Rate = k[X] [Y] [Z]
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ K_{C}=\frac{[M]}{[X][Y]}\Rightarrow [M]=K_{C}[X][Y] $ Rate $ =K’[M][Z]=K’K_{C}[X][Y][Z] $
$ =K[X][Y][Z] $
