Benzene has a heat of vaporization of 30.72 kJ/mol and a normal boiling point of 80.1 degrees C. At what temperature does benzene boil when the external pressure is 430 torr ? Express your answer in degrees Celsius using two significant figures.
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...
