$\mathrm{k}_{1}=2.5 \times 10^{5} \mathrm{L} \mathrm{mol}^{-1} \mathrm{s}^{-1}, \mathrm{k}_{-1}=1.0 \times 10^{4} \mathrm{s}^{-1}$ and $\mathrm{k}_{2}=10 \mathrm{s}^{-1}$. Under steady state approximation, the rate constant for the overall reaction in $\mathrm{L} \mathrm{mol}^{-1} \mathrm{s}^{-1}$ (rounded off to the nearest integer) is ____ .
