What would be the largest effect on the ideal gas law if there is a small attractive force between gas molecules?

Transcribed image text: uld be the largest effect on the ideal gas law if there is a small attractive force between gas molecules? At high densities, the volume would be larger than that predicted by the ideal gas law C. At high densities, the pressure would be greater than that predicted by the ideal gas law.

Does the size of a gas molecule affect pressure?

An increase in the number of gas molecules in the same volume container increases pressure.

Which factor is the major cause for deviation from ideal behavior the volume of the molecules or the attractive forces between them?

The Effect of Intermolecular Forces. At high pressures and low temperatures, intermolecular forces between gas particles can cause significant deviation from ideal behavior.

Which of the following gases would experience the greatest deviation from ideal behavior at high pressures?

Keeping that in mind, Xe is the largest of the bunch, and therefore is expected to have the greatest deviation of the ideal gas when under high pressure or low temperature.

In which gas sample would you observe the greatest deviation from ideal behavior?

What are the main reasons that gases deviate from ideal behavior?

Explanation: An ideal gas is a gas that follows the assumptions of the Kinetic Molecular Theory of Gases (KMT). Real gases deviate from ideal behavior because 1) they have intermolecular forces between molecules, 2) collisions aren’t always elastic (also due to intermolecular forces), and 3) gas molecules have volume.

How does molecular size affect pressure?

The pressure decreases as the molecular weight increases because the speed of the molecules moving in a sealed container would decrease according to Newtons second Law of motion.

Which gas would deviate the most from ideal behavior?

It is also good to know that ideal gas law assumes that the gas molecules have negligible/no size. Keeping that in mind, Xe is the largest of the bunch, and therefore is expected to have the greatest deviation of the ideal gas when under high pressure or low temperature.

What are the causes of deviation from ideal Behaviour?

Hint: The deviation of gases from the ideal behavior is basically dependent on the two main factors, the volume of the molecules of the gases and the force of attraction between the molecules of the gases. The collisions between the molecules of gas are assumed as perfectly elastic.
