Verified step by step guidance1
Understand the concept of an ideal gas: An ideal gas is a hypothetical gas that perfectly follows the ideal gas law, which is expressed as \( PV = nRT \), where \( P \) is pressure, \( V \) is volume, \( n \) is the number of moles, \( R \) is the ideal gas constant, and \( T \) is temperature.
Recognize the conditions under which real gases deviate from ideal behavior: Real gases deviate from ideal behavior at high pressures and low temperatures, where intermolecular forces and the volume occupied by gas molecules become significant.
Consider the molecular structure and intermolecular forces: Gases with stronger intermolecular forces or larger molecular sizes are more likely to deviate from ideal behavior. Carbon dioxide (\( CO_2 \)) has a larger molecular size and stronger intermolecular forces compared to the other gases listed.
Compare the gases: Nitrogen (\( N_2 \)), Neon (\( Ne \)), and Helium (\( He \)) are smaller and have weaker intermolecular forces compared to Carbon dioxide (\( CO_2 \)).
Conclude which gas is least likely to behave ideally: Based on the molecular size and intermolecular forces, Carbon dioxide is the gas that does not behave ideally under standard conditions.
