Non-ideal behavior for a gas is most likely to be observed under conditions of a) high pressure and low temperature. b) high temperature and high pressure. c) high temperature and low pressure. d) standard temperature and pressure. e) low temperature and low pressure.

high temperature and low pressure

Explanation:

Real gases have intermolecular forces of attraction between them hence they can be liquified. However, gases approach ideal behavior at high temperature and low pressure.

According to the kinetic theory of gases, gases molecules move at incredibly high speeds and exhibit no intermolecular interaction because the gas molecules are isolated from each other.

At high temperature and low pressure, gas molecules are found to possess maximum kinetic energy. They move with a very high velocity and have minimal intermolecular interaction between them in accordance with the proposition of the kinetic theory of gases.
