Chemical Kinetics

For the reaction \(\mathrm{A}+\mathrm{B} \rightarrow\) product, rate of reaction is \(3.6 \times 10^{-2} \mathrm{mol~dm}^{-3} \mathrm{sec}^{-1}\). When \([\mathrm{A}]=0.2 \mathrm{~mol} \mathrm{dm}^{-3}\) and \([\mathrm{B}]=0.1 \mathrm{~mol} \mathrm{~dm}^{-3}\), find rate constant of reaction if it is second order with respective to both reactants.
