Which of the following is not a valid assumption of the kinetic theory model for an ideal gas?

There are no attractive or repulsive intermolecular forces acting between the gas molecules except during collisions.
The duration of a collision of a molecule with the chamber wall is significantly greater than the time elapsed between collisions.
All collisions between the gas molecules and the chamber walls are perfectly elastic.
