Explain Collision theory and how increasing temperature impacts reaction rates.
Collision theory: reactions occur when particles collide with sufficient energy and correct orientation. Increasing temperature raises particle kinetic energy, causing more frequent and more energetic collisions, so more collisions exceed the activation energy and the rate increases.
