Activation Energy Diagram

Exothermic Reaction

Exothermic Reaction

Products have less energy than reactants

Endothermic Reaction

Products have more energy than reactants

Reactants

Chemicals put into reaction and at very left of graph

Activated Complex

Highest point; highest energy and most unstable; bonds not broken or formed

Products

Output of reaction; Far right of graph

Catalyst

Results it lower peak due to it introducing a path of lower activation energy
