3.6 Deviation from the Ideal Gas Law

The particle volume of Ar is greater than Ne

Ar atoms have more valence electrons than Ne atoms have, so Ar atoms have greater interparticle forces.

The intermolecular forces between Ne atoms are greater than those between Ar atoms.

Ar atoms are more attracted to the walls of the container than Ne atoms are.

The gas in sample 1 would deviate more from ideal behavior because the average distance an Xe atom travels before colliding with another Xe atom is greater.

The gas in sample 2 would deviate more from ideal behavior because the Xe atoms are closer together, leading to an increase in intermolecular attractions.

The gas in sample 2 would deviate more from ideal behavior because the average speed of the Xe atoms is less, leading to an increase in intermolecular attractions.

The gases in both sample 1 and sample 2 would show the same deviation from ideal behavior.

NH₃ molecules are polar while CH₄ molecules are not, and the greater attractions between NH₃ molecules cause the molecules to collide with the walls of the container with less force.

NH₃ molecules have a greater molar mass than CH₄ molecules, so the NH₃ molecules collide with the walls of the container with more force.

CH₄ molecules have more hydrogen atoms than NH₃ molecules, so CH₄ molecules have more hydrogen bonding and greater intermolecular forces.

CH₄ molecules are larger than NH₃ molecules, so the actual CH₄ molecules take up a significant portion of the volume of the gas.
