The vapor pressure of benzene is found to obey the empirical equation torr T T2 In (P) = 16.725 – 3229.86 K _ 118345 K? from 298.2 K to its normal boiling point 353.24 K. Given that the molar enthalpy of vaporization at 353.24 K is 30.8 kJ mol-1 and that the molar volume of liquid benzene at 353.24 K is 96.0 cm3 mol-1, use the above equation to determine the molar volume of the vapor at its equilibrium pressure...

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...

Please show all work and explanations! Calculate ΔE, ΔS, ΔG, Q and W for the vaporization of 3.00 moles of liquid water to form water vapor at 100°C and 1.00 atm pressure. The standard molar enthalpy of vaporization of water is 40.67 kJ/mol. The density of liquid water at 100°C is 0.958 g/cm3 . Assume that the water vapor is an ideal gas, but be careful – the initial state is liquid water, so this is not simply an ideal...
