Bond Energy Calculations
In exothermic reactions, energy is transferred from the chemicals to the surroundings.
Exothermic energy changes are shown as negative because energy has been transferred from the chemicals.
-
In endothermic reactions, energy is gained from the surroundings.
-
-
When we break a chemical bond, this requires energy (endothermic)
