Exothermic and endothermic reactions Flashcards
1
Q
What is chemical potential energy?
A
Energy stored in chemical bonds
2
Q
What is the law of the conservation of energy, and what does this imply in chemical reactions?
A
Energy is not created or destroyed, only transferred, thus products of a reaction are the same as the reactants
3
Q
What is an exothermic reaction?
A
Products have less potential energy than the reactants
Energy released into surroundings
4
Q
What is an endothermic reaction?
A
Products have more potential energy than the reactants
Energy absorbed from surroundings
