Order of reaction is zero as unit of rate constant is mole per second.

For a zero order reaction, concentration of reactant

\mathrm{A= A 0-K t }

\mathrm{\Rightarrow A=5 M-5 \times 10^{-3} \times 10 \times 60 M \\}

\mathrm{ \Rightarrow A=5 M-3 M }

Since, concentration of reactant is reduced by 3M, the concentration of product is 3M after 10 minutes.
