For a zero order reaction, $\mathrm{K}=1\times {10}^{-3}\mathrm{mol}{\mathrm{L}}^{-1}{\mathrm{s}}^{-1}$. If initial concentration of the reactant is $1.0\mathrm{mol}{\mathrm{L}}^{-1}$, the concentration after $10$ minutes would be

Consider the following in respect of zero order reaction

I. ${\mathrm{t}}_{1/2}$ is directly proportional to the initial concentration

II. Time taken for the completion of the reaction is twice its ${\mathrm{t}}_{1/2}$

III. Concentration of the reactant decreases linearly with time

Which of the statements given above are correct?
