Question

what does this piece of evidence best support?
the collision theory
the maxwell - boltzmann distribution
the effect of pressure on reaction rates
the effect of temperature on reaction rates

Explanation:

The diagram shows reactant molecules (blue and red - gray combinations) colliding, forming an activated complex (top), and then producing products. Collision theory states that reactions occur when particles collide with sufficient energy and correct orientation. The other options: Maxwell - Boltzmann is about energy distribution, pressure/temperature effects relate to rate factors but the diagram focuses on particle collisions leading to reaction, matching collision theory.

Answer:

A. the collision theory
