Chemical Kinetics

For the reaction $2\text{NOBr}_{(g)} \rightarrow 2\text{NO}_{(g)} + \text{Br}_{2(g)}$ rate law is $r = k[\text{NOBr}]^2$, if rate constant is $1 \cdot 62 \text{ mol dm}^{-3}\text{ s}^{-1}$ and concentration of NOBr is $2 \times 10^{-3} \text{ mol L}^{-1}$. What is the rate of reaction ?
