Predict: What happens if you double the concentration?
Collision theory: Reactions happen when particles collide with enough energy and the correct orientation.
Higher temperature = faster particles = more frequent, energetic collisions.
Higher concentration = more particles in the same space = more collisions.
Greater surface area = more exposed particles available to collide.
