Calculate the minimum power required to convert 1 mole/sec of oxygen gas at 298 K and 1 atm to saturated liquid oxygen at 1 atm and 90.13 K (the atmospheric pressure boiling temperature) in a process in which heat is rejected to the environment at 298 K. The following data are available for oxygen constant pressure heat capacity for oxygen gas = 29.14 J/mole K heat of vaporization at 90.13 K = 6820 J/mole.
