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...

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...

For a newly discovered chemical compound, it was determined that the vapor pressure can be estimated with the following equation over a range of temperatures that includes the compound's boiling point: = exp(-4 + B), where A = 4,000 K and B = 20 Р Calculate the molar enthalpy of vaporization for this compound. You can assume ideal gas behavior of the vapor. (As an approximation for the gas constant, you can...
