Chemical Kinetics Question 86
Question: For the reaction $ 2N_2{O_{5(g)}}\to 4N{O_{2(g)}}+{O_{2(g)}} $ , if concentration of $ NO_2 $ in 100 seconds is increased by $ 5.2\times {10^{-3}}m $ . Then rate of reaction will be [Kerala CET 2005]
Options:
A) $ 1.3\times {10^{-5}}m{s^{-1}} $
B) $ 5\times {10^{-4}}m{s^{-1}} $
C) $ 7.6\times {10^{-4}}m{s^{-1}} $
D) $ 2\times {10^{-3}}m{s^{-1}} $
E) $ 2.5\times {10^{-5}}m{s^{-1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ 2N_2{O_{5(g)}}\to 4N{O_{2(g)}}+{O_{2(g)}} $ Rate of reaction with respect to $ NO_2 $
$ =\frac{1}{4}\frac{d[NO_2]}{dt}=\frac{1}{4}\times \frac{5.2\times {10^{-3}}}{100}=1.3\times {10^{-5}}m{s^{-1}} $
