Chemical Kinetics Question 219
Question: The half-life of a first order reaction having rate constant K = 1.7 ´ 10-5 s-1 is [BHU 2005]
Options:
A) 12.1 h
B) 9.7 h
C) 11.3 h
D) 1.8 h
Show Answer
Answer:
Correct Answer: C
Solution:
$ K=1.7\times {10^{-5}}{s^{-1}} $
$ {t_{1/2}}=\frac{0.693}{K}=\frac{0.693}{1.7}\times 10^{5}=11.32h $
