Key terms
- Endothermic reaction: A reaction that takes in energy from the surroundings. In Energy transfer during exothermic and endothermic reactions, this term is used specifically to support the learning objective: identify thermal decomposition and the reaction of citric acid with sodium hydrogencarbonate as examples of endothermic reactions.
- Thermal decomposition: A type of endothermic reaction where a compound breaks down into simpler substances when heated.
Common trap
Confusing Endothermic Reactions: Remember that thermal decomposition is an endothermic reaction that takes in energy from the surroundings, while exothermic reactions release energy.
