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}} $
