Phase 1: Ideal Behavior Deviation Factors.
Deviations in gas behavior from the ideal model stem from intermolecular attractions and the physical volume of gas particles. These discrepancies escalate at elevated pressures.
Phase 2: Intermolecular Force Assessment.
Hydrogen and Helium, being lightweight, possess negligible intermolecular forces.
Neon, a noble gas, exhibits weak van der Waals forces.
Carbon dioxide, a larger and more polarizable molecule, experiences stronger intermolecular attractions, resulting in more pronounced deviations.
Phase 3: Determination.
Under high pressure conditions, Carbon dioxide demonstrates the greatest deviation from ideal gas behavior, attributed to its substantial van der Waals forces and molecular dimensions.
