Neco Model Questions Vol1 2024 Chemistry Question 33
Practice objective / multiple choice question 33 from the 2024 Neco Model Questions Vol1 Chemistry examination.
The enthalpy of vaporisation of liquid A is \(\Delta H_{\text{vap}} = 30\ \text{kJ mol}^{-1}\). Its vapour pressure follows the Clausius-Clapeyron relation \(\ln P = -\dfrac{\Delta H_{\text{vap}}}{R T} + C\). At \(60^{\circ}\text{C}\) the vapour pressure is 150 mm Hg. Calculate the vapour pressure of A at \(100^{\circ}\text{C}\). (Take \(R = 8.314\ \text{J mol}^{-1}\text{K}^{-1}\)).
