A gas such as carbon monoxide would be most likely to obey the ideal gas law at

Options

A. high temperature and high pressure
B. low temperatures and low pressures
C. high temperature and low pressures
D. low temperatures and high pressures

Answer

C

Explanation

For real gases
`(P+(an^(2))/(V^(2)))(V-nb)=nRT` . . . (1)
At high temperature intramolecular attractive forces are neglected i.e., `(an^(2))/(V^(2))` term is neglected. At low pressure volume is high so nb term is neglected.
Hence from equation (1) PV=nRT
