The enthalpy of vaporization of a liquid at its boiling point $\left(T_{b}=200 \mathrm{K}\right)$ is $15.3 \mathrm{kJ} \mathrm{mol}^{-1}$. If the molar volumes of the liquid and the vapour at 200 K are 100 and $12000 \mathrm{cm}^{3} \mathrm{mol}^{-1}$, respectively, then the slope $\frac{\mathrm{dP}}{\mathrm{dT}}$ of the liquid boundary is ____ $\mathrm{kPa} \mathrm{K}^{-1}$ (Upto two decimal places. Note : $1 \mathrm{Pa}=1 \mathrm{J} \mathrm{m}^{-1}$ )
