Energy Changes Flashcards
1
Q
What is a exothermic reaction and what are examples of one?
A
A reaction where energy is transferred to the surroundings and as the surroundings have more energy then they started with so the temperature also increases.
Examples are: combustion reactions, oxidation reactions and neutralisation reactions.
2
Q
What are endothermic reactions and what are examples of one?
A
A reaction where energy is taken in from the surroundings. The surroundings then have less energy and the temperature decreases.
Examples are: thermal decomposition reactions and the reaction between citric acid and sodium hydrogencarbonate.
