Chemical Kinetics Question 88
Question: For the reaction $ 2N_2O_5\to 4NO_2+O_2 $ rate of reaction and rate constant are $ 1.02\times {10^{-4}} $ and $ 3.4\times {10^{-5}}{{\sec }^{-1}} $ respectively. The concentration of $ N_2O_5 $ at that time will be [BHU 2001]
Options:
A) $ 1.732 $
B) 3
C) $ 1.02\times {10^{-4}} $
D) $ 3.4\times 10^{5} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ R=K[A] $ , $ 1.02\times {10^{-4}}=3.4\times {10^{-5}},,[N_2O_5] $ or $ (N_2O_5) $
$ =\frac{1.02\times {10^{-4}}}{3.4\times {10^{-5}}},,K=3 $
