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

    A) \[{{t}_{\frac{1}{2}}}=\frac{a}{2k}\]                

    B) \[-{{t}_{\frac{1}{2}}}=ka\]

    C) \[{{t}_{\frac{1}{2}}}=\frac{a}{k}\]                  

    D) \[{{t}_{\frac{1}{2}}}=\frac{k}{a}\]

    Correct Answer: A

    Solution :

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