At 1 atm, dioxygen O2 is solid below −218.8 ◦C, liquid between −218.8 and −183.0 ◦C, and gaseous above −183.0 ◦C. At 1 atm, O2 will follow the ideal-gas law most closely
(A) above +80.0 ◦C. (B) between −20.0 and +10.0 ◦C. (C) between −183.0 and −80.0 ◦C. (D) close to −183.0 ◦C. (E) below −183.0 ◦C.
Homework Answers
As the volume of 1 mol of O2 is close to 22.4 L for option B, so it will behave close to ideal at this temperature, moreover at lower temperature there will be higher intermolecular attractions, most appropriate answer is B

A gaseous stream containing 20.0 mole% ethanol and 80.0 mole% air is to be cooled from 60.0°C to 9.65°C in a condenser at the constant pressure of 1 atm to liquefy some of the ethanol. The gas stream entering the condenser has a pressure of 1.00 atm, flows at a rate of 10.0 mole/s and, at 60°C, is well above the saturation temperature (42.4°C). As a result of the cooling, 1.75 mole/s of liquid ethanol (Tbp = 78.5°C) leaves the...
