A real gas would be most likely to obey the ideal gas laws at

Step-by-step solution

Real gas shows ideal gas behaviour at high temperature and low pressure. e.g. Carbon monoxide (CO) would be most likely to obey the ideal gas law. Under high temperature and low pressure, the volume V is very large and terms in real gas i.e. ‘ a V^2 and b can be neglected. Hence, van der Waals' equation reduce to ideal gas equation, p V=n R T .
