According to the Clausius-Clapeyron equation ln va R T T P"арф) refers to the vapor pressure at temperature 1, R-2 cal/mol-K, and Ah is the heat of changc associated with the process of transitioning to the vapor (cither sublimation or vaporization depending on whether the transition is from solid to vapor or liquid to vapor) i.e., дН-H vapor-H , where X is either solid or liquid and H denotes the corresponding molar enthalpy. Use the Clausius-Clapeyron equation to solve...
For a given pure substance, vapor pressure values were determined experimentally in equilibrium with the solid and liquid phases, at different temperatures, from which the following ratios were deduced: Solid / vapor equilibrium: ln (p / mmHg) = 17.44 - 939.7 / (T / K) Liquid / vapor balance: ln (p / mmHg) = 16.02 - 820.0 / (T / K) a) Determine the coordinates (p, T) of the triple point of the substance. b) Assuming that the enthalpy values...
1. The normal boiling point of benzene (i.e., at 1 atm) is 80.09 °C. The molar enthalpy of vaporization is 30.72 kJ mol . Assuming that AvapHm and AvapSm stay constant at their values at 80.09°C, calculate the values of AvapGm at 75.0 °C, 80.09 °C and 85.0 °C. Given your calculated values, do you still expect benzene to spontaneously condense at 75.0 °C and to spontaneously evaporate at 85.0°C? -1 2. The vapor pressure of a liquid was measured...
