Neco Model Questions Vol1 2017 Chemistry Question 8
Practice objective / multiple choice question 8 from the 2017 Neco Model Questions Vol1 Chemistry examination.
At 350\,K, the coexistence line between liquid and vapour of a certain substance has a slope \(\frac{dP}{dT}=0.013\,\text{atm·K}^{-1}\). The molar volume of the vapour at this temperature is 24.5\,L·mol^{-1}, while the liquid molar volume is negligible. Using the Clapeyron equation, calculate the enthalpy of vapourisation \(\Delta H_{vap}\) (in kJ·mol^{-1}) at 350\,K.
