Neco 2020 Chemistry Question 45
Practice objective / multiple choice question 45 from the 2020 Neco Chemistry examination.
The vapor pressure of ammonia at 25 °C is 8.5 kPa and its molar enthalpy of vaporisation is \(\Delta H_{\text{vap}} = 23.3 \text{ kJ mol}^{-1}\). (a) Using the Clausius-Clapeyron equation, estimate the vapor pressure at 35 °C. (b) Assuming the same \(\Delta H_{\text{vap}}\) applies, estimate the temperature at which the vapor pressure equals 101.3 kPa (1 atm), i.e., the boiling point at 1 atm.
