How does increasing concentration affect collisions according to the particle model?

Explanation:
Increasing concentration means more particles in the same space. In the particle model, these particles are constantly moving and colliding with one another. With more particles per volume, there are more possible collisions, so the collision frequency goes up. This higher collision frequency is why reactions tend to occur faster when concentration is increased. Color changes aren’t the direct result of collision frequency; they depend on how light interacts with dissolved particles, not on how often particles collide.
