3.6 Deviation from Ideal Gas Law

Explain the relationship among non-ideal behaviors of gases, interparticle forces, and/or volumes.

• The ideal gas law does not explain the actual behavior of real gases. Deviations from the ideal gas law may result from interparticle attractions among gas molecules, particularly at conditions that are close to those resulting in condensation. Deviations may also arise from particle volumes, particularly at extremely high pressures.
