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

If doubling the initial concentration of reactant doubles $t_{1/2}$ of reaction,the order of reaction is

The rate constant of a zero-order reaction is $0.2 \ mol \ L^{-1} \ hr^{-1}$. If the concentration of the reactant after $0.5 \ hr$ is $0.05 \ M$,then the initial concentration of the reactant is ....... $M$.

For a zero order reaction,the plot of concentration $(a-x)$ $Vs$ time is linear with

The rate constant of a zero-order reaction is $0.2 \ mol \ m^{-3} \ h^{-1}$. If the concentration of the reactant after $30 \ minutes$ is $0.05 \ mol \ m^{-3}$,then its initial concentration will be ....... $mol \ m^{-3}$.

Which of the following statements is true?
