Chemical Kinetics Question 127
Question: Half life period of a first order reaction is 138.6 minutes. The velocity constant of the reaction is
Options:
A) $ 0.05,{{\min }^{-1}} $
B) $ 0.00005,{{\min }^{-1}} $
C) $ 0.005,{{\min }^{-1}} $
D) $ 200,{{\min }^{-1}} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ K=\frac{0.693}{{t_{1/2}}},K=\frac{0.693}{138.6\min }=0.005{{\min }^{-1}} $
