For a zero-order reaction with rate constant $k$,the slope of the plot of reactant concentration against time is

The unit of velocity constant in case of zero order reaction is

For a zero order reaction,the plot of concentration of reactant $vs$ time is (Hint: Consider the intercept on the concentration axis)

For a zero order reaction,a plot of $t_{1/2}$ versus $[A]_0$ will be

If $c_o$ is the initial concentration of the reactant,what will be the half-life period for a zero-order reaction?

The reaction $2X \to B$ is a zeroth order reaction. If the initial concentration of $X$ is $0.2 \ M$,the half-life is $6 \ h$. When the initial concentration of $X$ is $0.5 \ M$,the time required to reach its final concentration of $0.2 \ M$ will be ........ $hr$.
