Collisions Theory

Subject: Chemistry

Book: General Chemistry

Collision theory states that for a reaction to occur, reacting molecules must collide with sufficient energy (≥ Ea) and proper orientation. Increasing temperature raises molecular velocities, boosting collision frequency and energy. Catalysts provide alternative pathways or orientations, reducing the effective Ea. Collision theory provides a conceptual basis for understanding reaction kinetics and rate laws.
