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} $
