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 colliding (forming an activated complex at the peak) and then forming products. Collision theory states that chemical reactions occur when particles collide with sufficient energy and correct orientation. The Maxwell - Boltzmann distribution is about energy distribution of particles, not shown here. Pressure and temperature effects aren't directly depicted (no pressure or temperature - related indicators like volume change or temperature labels). So the evidence best supports collision theory.

Answer:

the collision theory
