Neco 2018 Chemistry Question 8
Practice objective / multiple choice question 8 from the 2018 Neco Chemistry examination.
The normal boiling point of liquid A is 350 K and its molar enthalpy of vaporisation is \(\Delta H_{\text{vap}} = 30.0\) kJ·mol\(^{-1}\). Assuming the molar volume of the liquid is negligible compared with that of the vapour, estimate the vapour pressure of A at 300 K. Use \(R = 8.314\) J·mol\(^{-1}\)·K\(^{-1}\) and give your answer in kPa.
