19.【计算题】 vaporizven the molar enthalpy of vaporization of ethanol C₂H5OH at normal boiling temperature 78.8 °C is 43.5 kJxmol-1. 2 mol of ethanol C2H5OH (1) with temperature of 78.8 °C E 5010560 pressure of 100 kPa vaporizes into gas with the same temperature and pressure at an external pressure of Pext=0. Suppose the volume of liquid can be neglected in comparison with that of vapor. The vapor can be treated as *** an ideal gas. 21 Q: Calculate AH, AU, w, q, AS, AA and AG for this process. (14 Points)
