Chemical Kinetics Question 105
Question: The first order rate constant for the decomposition of $ N_2O_5 $ is $ 6.2\times {10^{-4}}{{\sec }^{-1}} $ . The half life period for this decomposition in seconds is [MNR 1991; MP PET 1997; UPSEAT 2000]
Options:
A) 1117.7
B) 111.7
C) 223.4
D) 160.9
Show Answer
Answer:
Correct Answer: A
Solution:
$ {t_{1/2}}=\frac{0.693}{k}=\frac{0.693}{6.2\times {10^{-4}}}=1117.7 $ sec.
