The vapour pressure of a liquid in the temperature range 200K to 260 K was found to fit the expression In(p/Torr)- 18.361 - 3036.8/ (T/K ) . Calculate the enthalpy of vaporization of the liquid.
7. The vapour pressure of a liquid in the temperature range 200 K to 260 K was found to fit the expression ln(p/Torr) = 16.255 – 2501.8(T/K). What is the enthalpy of vaporization of the liquid?
1. At equilibrium, the rate of change of vapor pressure to temperature for the vaporization process of a liquid is expressed by the following Clausius - Clapeyron equations: ΔΗναp dT din P= RT2 with Hvap is the enthalpy of vaporization. Starting with the chemical potential, derive the Clausius - Clapeyron equation.
1) The enthalpy of vaporization for a liquid is found to be 14.4 kJ mol- at 180 K, its normal boiling point. The molar volumes of the liquid and the vapour at the boiling point are are 115 mL mol-1, and 14.5 L mol-1, respectively. a) Use the Clapeyron equation to estimage the temperature dependence of the vapour pressure (dp/dT) at the normal boiling point. b) Use the Clausius-Clapeyron equation to estimate dp/dT. c) Does the Clausius-Clapeyron equation overestimate or...
