Igcse Model Questions Vol1 2017 Chemistry Question 3
Practice objective / multiple choice question 3 from the 2017 Igcse Model Questions Vol1 Chemistry examination.
The vapour pressure of a liquid is \(0.12\ \text{atm}\) at \(298\ \text{K}\) and \(0.25\ \text{atm}\) at \(308\ \text{K}\). Using the Clausius-Clapeyron equation, calculate the enthalpy of vapourisation \(\Delta H_{\text{vap}}\) in \(\text{kJ mol}^{-1}\). (Take \(R = 8.314\ \text{J mol}^{-1}\text{K}^{-1}\)).
