Chemical Kinetics Question 341

Question: The rate equation for a reaction, $ N_2O\xrightarrow{{}}N_2+1/2O_2 $ is Rate $ =k{{[N_2O]}^{0}}=k. $ If the initial concentration of the reactant is a mol $ Li{t^{-1}} $ , the half-life period of the reaction is

Options:

A) $ {t_{\frac{1}{2}}}=\frac{a}{2k} $

B) $ -{t_{\frac{1}{2}}}=ka $

C) $ {t_{\frac{1}{2}}}=\frac{a}{k} $

D) $ {t_{\frac{1}{2}}}=\frac{k}{a} $

Show Answer

Answer:

Correct Answer: A

Solution:

[a] For a zero order reaction $ {t_{1/2}}=\frac{a}{2k} $
