Could somebody help me with some Chemistry questions?

Question

Taking into account kinetic theory and collision theory...

Are attractive and repulsive forces between particles strong?
Are particles small spheres of insignificant volume?
Is energy conserved when particles collide?
Do particles move in random curved lines?
Must particles collide in the proper orientation to react?

Answer 1

Are attractive and repulsive forces between particles strong?

Depends on the inter particle distance

All the rest are assumptions made by the kinetic theory.
