Final answer:
Collision theory is essential for understanding chemical reactions as it clarifies how reactant particles must collide effectively for a reaction to take place.
Explanation:
Collision theory is crucial when studying a chemical reaction as it explains how reactant particles must collide with sufficient kinetic energy and correct orientation for a reaction to occur. Effective collisions result in products being formed, while ineffective collisions only lead to particles bouncing off each other unchanged. Temperature and concentration play vital roles in increasing the likelihood of successful collisions and thus reaction rates.
