Energy cannot be created or destroyed, only transferred
The chemical reaction being studied
Everything outside the reaction (container, environment)
Reaction that releases energy to the surroundings
Temperature goes up
Reactants have more energy than products
Reaction that absorbs energy from the surroundings
Temperature goes down
Products have more energy than reactants
Energy must be absorbed from surroundings
Energy is released to the surroundings
Energy Change=Sum of Bonds Broken−Sum of Bonds Made\text{Energy Change} = \text{Sum of Bonds Broken} - \text{Sum of Bonds Made}Energy Change=Sum of Bonds Broken−Sum of Bonds Made
Exothermic reaction (energy released overall)
Endothermic reaction (energy absorbed overall)
