Exothermic and endothermic reactions Flashcards
1
Q
What is an exothermic reaction?
A
reaction that transfers energy to the surroundings
e.g. combustion, neutralisation
everyday uses include self heating cans and hand warmers
2
Q
What is an endothermic reaction?
A
a reaction that takes in energy from the surroundings
e.g. thermal decomposition
sports injury packs are based upon endothermic reactions
3
Q
What happens in a reversible reaction?
A
if a reversible reaction is endothermic in one direction, and exothermic in the opposite direction:
the same amount of energy is transferred in each case
