Resource summary
Chemistry Unit 2.5 - Exothermic and Endothermic Reactions
Chemical reactions involve energy transfers
Many chemical reactions involve the release of energy
For other chemical reactions, energy must be supplied
When chemical reactions occur, energy is transferred to or from the surroundings
Exothermic reaction
One that transfers energy to the surroundings
Examples include combustion, many oxidisation reactions and neutralisation
Everyday uses of exothermic reactions include self-heating cans (e.g. for coffee) and hand warmers
Endothermic reaction
One that takes in energy from the surroundings
Examples include thermal decompositions
Some sports-injury packs are based on endothermic reactions
If a reversible reaction is exothermic in one direction it is endothermic in the opposite direction
The same amount of energy is transferred in each case
