The enthalpy of vaporization of a liquid at its boiling point (Tᵦ = 200 K) is 15.3 kJ mol⁻¹. If the molar volumes of the liquid and the vapour at 200 K are 110 and 12000 cm³ mol⁻¹ respectively, then the slope
of the liquid-vapour boundary is ________ kPa K⁻¹. (Up to two decimal places. Note: 1 Pa = 1 J m⁻³)Log in to check the answer
