Chemical Kinetics Question 113
Question: The decomposition of $ N_2O_5 $ is a first order reaction represented by $ N_2O_5\to N_2O_4+\frac{1}{2}O_2 $ . After 15 minutes the volume of $ O_2 $ produced is $ 9,ml $ and at the end of the reaction $ 35,ml $ . The rate constant is equal to [MP PET 1995]
Options:
A) $ \frac{1}{15},\ln ,\frac{35}{44} $
B) $ \frac{1}{15},\ln ,\frac{44}{26} $
C) $ \frac{1}{15},\ln ,\frac{44}{35} $
D) $ \frac{1}{15},\ln ,\frac{35}{26} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ K=\frac{1}{t}\log e( \frac{a}{a-x} )=\frac{1}{15}\log e( \frac{35}{35-9} ) $
$ =\frac{1}{15}\log e( \frac{35}{26} ) $
