When the initial concentration of the reactant is doubled,the half-life period of a zero order reaction:

If the rate of the reaction is equal to the rate constant,the order of the reaction is

The rate equation for a reaction $A \rightarrow B$ is $r=k[A]^{0}$. If the initial concentration of the reactant is $a \ mol \ dm^{-3}$,the half-life period of the reaction is
