The collision theory is "the theory that reactions happen when molecules collide." The theory helps to explain the ... frequent, harder, and more successful and fruitful collisions between the particles. At low temperatures or when you decrease the temperature, the rate of reaction decreases because the molecules have less kinetic energy; therefore they move around slower so collisions become weaker a...
