Chemical Kinetics Question 162
Question: For a first order reaction, rate constant is $ 0.6932,h{r^{-1}} $ , then half-life for the reaction is [Bihar MEE 1997]
Options:
A) $ 0.01,hr $
B) $ 1,hr $
C) $ 2,hr $
D) $ 10,hr $
E) $ 0.1,hr $
Show Answer
Answer:
Correct Answer: B
Solution:
$ {t_{1/2}}=\frac{0.693}{k}=\frac{0.693}{0.6932h{r^{-1}}}=1hr $ .
