Collisions, energy barriers, and profile shape

Collisions, energy barriers, and profile shape

Side-by-side reaction profiles showing an exothermic reaction with products lower than reactants and an endothermic reaction with products higher than reactants; both show activation energy and overall energy change arrows

Chemical reactions only happen when particles collide, but not every collision works. The particles must collide with enough energy to get over the activation energy barrier.
