Chemical Kinetics Question 139
Question: Value of velocity constant for first order reaction is $ 3.46\times {10^{-3}}{{\min }^{-1}} $ , the time for half change is
Options:
A) 100 minutes
B) 400 minutes
C) 200 minutes
D) 346 minutes
Show Answer
Answer:
Correct Answer: C
Solution:
$ {t_{1/2}}=\frac{0.693}{k}=\frac{0.693}{3.46\times {10^{-3}}}=200,min $
