A reaction involving A and B is found to be zero order with respect to A and second order with respect to B. When the initial concentrations of A and B are 1.0×10−3 mol dm−31.0 \times 10^{-3} \text{ mol dm}^{-3} and 2.0×10−3 mol dm−32.0 \times 10^{-3} \text{ mol dm}^{-3} respectively, the initial rate of the reaction is 4.5×10−4 mol dm−3 min−14.5 \times 10^{-4} \text{ mol dm}^{-3} \text{ min}^{-1}. Calculate the value and units of the rate constant for the reaction.
