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