Under what conditions do you think the gas laws would deviate most from ideal behavior? The opposite of that is the answer to your question. Think along the lines of corrections to the ideal gas law of PV = nRT made by the van der Waals equation.
STP
Would it be n2a/V2?
STP is not where they deviate most. High pressures and low temperatures, where the molecules are close together (therefore there is more attraction between molecules), and where the volume of the molecules become more important.
