PCAT Chemical Processes – Gas

- PCAT Question of the Day
The behavior of gas will deviate from ideal behaviors LEAST under which of the following sets of conditions:
- A gas at high pressure and temperature
- A gas at low pressure and temperature
- A gas at high pressure and low temperature
- A gas at low pressure and high temperature
The ideal gas law, PV=nRT, is based on two assumptions: 1) individual molecular volume is negligible, and 2) intermolecular forces do not exist. A real gas at high temperature and low-pressure conditions, best approximates these two assumptions, and thus the ideal gas law. Therefore, answer choice D is the correct answer.
